To set the THERMO MODE and desired room temperature:
1. Press the MODE key until the LCD screen shows the word ROOM. Then the remote is in the
thermostatic mode.
2. Press and hold the SET key until the desired set temperature is reached. (By pressing and
holding the set key the LCD screen set numbers will increase from 45° to 99° and then restart
over at 45°).
3. Next release the SET key. The LCD screen will display the set temperature for 3 seconds and
the LCD screen will ash the set temperature for 3 seconds. Then the LCD screen will default
to display the room temperature.

REMOTE CONTROL OPERATION NOTES:
The Thermo Feature 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 -4 times per hour depending on how well the room or home is insulated from
the cold or drafts. The factory setting for the “swing number” is 2. This represents a temperature
variation of +/-2°F (1°C) between SET temperature and ROOM temperature, which determines
when the replace will be activated. The transmitter has ON and OFF manual functions that
are activated by pressing either button on the face of the transmitter. When a button on the
transmitter is pressed the word ON or OF will appear on the LCD screen to show while the
signal is being sent. Upon initial use, there may be a delay of three seconds before the remote
receiver will respond to the transmitter. This is part of the system’s design.
