SETTING DESIRED ROOM TEMPERATURE
This remote control system can be thermostatically controlled
when the transmitter is in the THERMO mode (THERMO must
be displayed on the screen). To set the DESIRED room
temperature, press the MODE button (Fig. 17) to place the
transmitter into THERMO mode, then press the UP or DOWN
buttons to select the desired room temperature. The highest
SET temperature is 99º Fahrenheit (32º Celsius).
OPERATIONAL NOTE: TO CONSERVE BATTERY POWER,
CHANGES IN ROOM TEMPERATURE ARE AUTOMATICALLY
UPDATED EVERY TWO MINUTES TO THE TRANSMITTER.

The Thermo Mode on the transmitter operates the appliance whenever the ROOM TEMPERATURE varies a certain
number of degrees from the SET TEMPERATURE. This variation is called the “SWING” or TEMPERATURE
DIFFERENTIAL. The normal operating cycle of an appliance may be 2-4 times per hour depending on how well the
room or home is insulated from the cold or drafts. A smaller “swing number” increases the number of cycles so the room
temperature is more constant. A larger “swing number” decreases the number of cycles, which saves energy, in most
cases. The factory setting for the “swing number” is 2. This represents a temperature variation of +/- 2º F (1º C) between
SET temperature and ROOM temperature, which determines when the replace will be activated. The “SWING” number
values are: 1=+ 1º F (.5º C), 2= + 2º F (1º C) and 3 = + 3º F (1.6º C).

SET
1. To change the temperature “SWING” setting (1-3), press
the TIMER/TIME and DOWN buttons simultaneously to
display the current “SWING” setting in the SET TEMP
frame. The letter “S” will display in the ROOM TEMP frame
on the LCD screen.
2. Press the UP or DOWN button to change the temperature
differential or “SWING” (1-3). See above for 1-3 “SWING”
temperature valves.
3. To store the “swing number press the SET button or allow
15-seconds to lapse, and the new “swing number’ will be
automatically programmed.

The operation of the factory set “THERMO SWING” can be checked by adjusting the SET TEMP 2º F above or below the
room temperature. This will cause the system to turn ON or OFF. Normally the system will only respond to temperature
changes every two minutes. Manually changing the SET temperature will activate the system in less than 10-seconds.
If the “SWING” is changed, then a new room temperature differential will respond. Remember the Factory setting of the
“SWING” temperature is 2º F.
