Read This Before Installing Thermostat

IMPORTANT

1. Read the entire installation section of this Owner's Manual thoroughly before you begin to install or operate your Ocean Breeze Thermostat.



INSTALLATION

2. All installation is normally performed at your thermostat.



PROGRAMMING

3. You can practice programming before installing your thermostat by inserting and connecting the batteries and following the instructions on page 6 to 11. This can be done while you relax in your favorite chair and is a very good way to familiarize yourself with all the functions of your Ocean Breeze Thermostat.



OPERATION

4. Your Ocean Breeze Thermostat is designed to operate with most gas, oil, electric or 2-wire hot water heating, and air conditioning systems that have 24-volt or millivolt control.

This Ocean Breeze Thermostat will not control multi-stage heating or cooling systems, 110/220V systems, or 3 wire zone systems.



COMPRESSOR PROTECTION

5. The thermostat provides a 4-minute delay after shutting off the compressor before it can be restarted. This feature will prevent damage to your air conditioner compressor caused by rapid cycling. It does not provide a delay when there are power outages.



TEMPERATURE RANGE

6. Your thermostat can be programmed between 40° F and 95° F (5° C and 35° C). However, it will display room temperatures from 32° F to 99° F (0° C to 37° C).



POWER FAILURE

7. Whenever the main power is interrupted or fails, the battery power retains the programs and current time.



BATTERY WARNING

8. When the batteries are low, "LOW BATT" indicator appears, the thermostat will continue to operate for approximately 30 days. (Only alkaline batteries should be used in your thermostat. Rechargeable batteries have different properties which may cause the thermostat to not operate properly. Do not use old batteries.) The batteries should last one year.

CAUTION: The batteries are the only source of power used to operate your system. If you do not replace the batteries, the display will dim and your heating and cooling system will stop operation.

NOTE: If you plan to be away from the boat over 30 days, we recommend that you replace the old batteries with new alkaline batteries prior to leaving.



How This Thermostat Works... And Saves You Money

This thermostat is designed to optimize the use of your heating and cooling equipment. It does this by matching your comfort (the temperatures in your boat) to your schedule.


An example:
6:00 am   You wake up. Program 1 has the heat set to 70° F (21° C).
7:30 am

  You leave for work. The second program turns the heat back to 62° F (17° C) while you are away.
5:00 pm

  You come home. The third program has already warmed your boat back to 70° F (21° C).
10:00 pm


  You go to bed. A half hour later, program 4 turns the heat back to 64° F (18° C) to save energy while you are under the blankets.




Installation

Mount Wallplate and Thermostat

Snap open the back cover from your thermostat by pressing the release tab on the bottom of the thermostat.

Position template on wall and mark cut out. Then cut thermostat opening. Pull four wires, red, green, yellow and white. Connect these wires by color code (red to red, etc.) to terminal block located on back plate of thermostat. Install thermostat to wall.




Selector Switches

The heating system selector and the F/C selector switches are located on the Printed Circuit Board.


Heating System Selector

The heating system selector is a switch on the Printed Circuit Board located on the inside of the thermostat.

Fig. 1 : Position the Heating System Selection switch to the "HE" position. This is the correct position for your marine unit.

NOTE: "HG: positon is for gas and most other systems. "HE" position is for certain electric systems having a fan relay.


F/C selector (Fahrenheit/Centigrade)


Your thermostat is set for F mode from the factory. In order to change to C mode, slide the switch to C and press reset button on the front of the thermostat with a paper clip. The reset button is located near the display.

NOTE: Unless reset button is pressed, the thermostat will not change the mode.



Connect Wires and Mount Thermostat Cover

Match and connect the wires to the appropriate coded terminal screws on the mounting plate.

Be sure to tighten the terminal screws securely, otherwise a loose wire could cause operational problems with your system or thermostat.

Push excess wire back into hole to prevent interference with mounting of the thermostat.

Make sure the Function Switch is set OFF, and the FAN-AUTO Switch is in AUTO.

Insert the bottom tab on the thermostat body to snap it into the wallplate. (NOTE: Do not force the thermostat onto the wallplate, as the terminal pins may be damaged. If it does not snap properly, the thermostat may not work.)

Switch on the main power. Press the reset button.

The LCD display indicates the current room temperature of your boat. If it shows random numbers or partial digits, press the reset button once again.

The installation is now complete. Continue reading Owner's Manual for complete operating instructions.




Programming

1. When the heating or cooling system is actually operating, "HEAT" or "COOL" will appear on the display.

2. If power is interrupted the batteries will keep all programs.

3. If "LOW BATT" indicator appears on the display replace the batteries.



Setting the Time and Day of Week

When you first install the two AA batteries, the thermostat automatically sets the day and time to Monday, 12:00 a.m., shows the current room temperature and is programmed for 68° (20° C) in heat mode and 78° F (25° C) in cool mode. Press the reset button after installing new batteries.

The first data you should enter is the current time and day of week. As the keys are pressed, the display will show the data being entered.



Typical Suggested Summer and Winter Programs for Maximum Savings

Studies conducted by the Department of Energy estimate that setting your thermostat back 10° F for two 8-hour periods during winter can reduce your fuel bill by as much as 30%. By setting your thermostat up 5° F for two 8-hour periods during summer you can reduce your fuel bill up to 25%. Your thermostat is capable of holding up to 4 separate programs for heat or cool for weekdays and 4 separate programs for each weekend day.

A typical set of programs is shown in Table 1.

NOTE: The thermostat program will NOT take effect immediately after programming of your thermostat but at the next programmed time/temperature change. The thermostat is pre-set to 68° F (20° C) for heat and 78° F (25° C) for air conditioning. So if you want a temperature other than 68° F or 78° F (20° C or 25° C) right away, use the temperature manual override feature (described on page 9 ) to enter your desired temperature setting.

When your program becomes effective at the next time/temperature setting, the appropriate correspending program number will appear on the display.

Programming Your Thermostat


Your thermostat can be programmed in two different ways.
1. Auto-program method
2. Manual method
Before programming position the Heat/Off/Cool selector to the mode to be programmed.

Auto-program method

In auto-program method, you can program your thermostat instantly for the entire week by simply pressing "Auto Prog." key once. When this key is pressed, standard program gets activated and your thermostat is programmed automatically. The standard program is shown in table 3.

If you wish to change this program to suit your life style, you can do so by changing the time and the temperatures of those programs which you want to be different than standard programs. The method is explained in the manual method of programming.

Press

Your thermostat will be programmed automatically according to Table 3.

Table 3

(If the slide switch is in the heat mode, only heat program is effective. In order to activate cool program, slide the switch to cool mode and press "Auto Prog.")

Manual method

In this method, each program is inserted according to your personal programming schedule.

When the battery is first inserted, the thermostat is programmed for 68° F (20° C) in heat mode and 78° F (25° C) in cool mode.

NOTE: There is no energy saving time or temperature settings.

Familiarize yourself with manual programming. The following example demonstrates the manual programming method. You can program or change the program of weekdays and weekends.

NOTE: 1. The program time is set in increments of 15 minutes.

2. The program temperature is set in increments of 1° F.


NOTE: If the program time remains 0:00 that particular program will not be effective; e.g., if Program #2 has time 0:00, the thermostat will jump from Program #1 to Program #3.

Reviewing Programs
You may want to review the programs to see that settings are compatible with your lifestyle.




Temporary Manual Override
In the following example, the present room temperature is 60° and we want to raise the temperature to 70° temporarily until the next program.

Operations

Filter Monitor

The OCEAN BREEZE programmmable thermostat measures and stores the amount of time the heating or air conditioning system operated.

After 500 hours of usage, the word "FILTER" will appear and flash on the display, reminding you to check or replace your system filter.




To Reset the Filter Counter to Zero



Filter indicator disappears

NOTE:"FILTER RESET" button works only when "FILTER" is shown on the display. If "RESET" button is pressed when "FILTER" is not displayed, the internal counter will not reset.


Other Features

Temperature Span

Your thermostat is pre-programmed at the factory to cycle when the temperature rises 1° above or1° below the temperature setting to provide maximum comfort. It cannot be changed.
