Skytech: TS-R-2A Wireless Thermostat
REV. 11-14-18 Page 3
SETTING °F / °C SCALE
The factory setting for temperature is degrees Fahrenheit (°F) . To change this setting to Centigrade (°C), you must press
and hold both the ON and OFF buttons on the transmitter at the same time until the LCD displays the change. If you want
to convert back, repeat the above procedure.
THERMO UPDATING FEATURE
This SKYTECH wired wall thermostat has a THERMO UPDATING Feature built into its software. The THERMO
UPDATING Feature operates in the following manner, but only in the THERMOSTAT MODE:
The TS-R-2A normally reads the ROOM temperature every 2 minutes checking the ROOM temperature against the SET
temperature and then sends a signal to the appliance.
NOTE: When locating the TS-R-2A on a wall remember it should be kept away from direct sources of heat such as
heating appliance, incandescent lighting, and direct sunlight. Leaving the TS-R-2A in direct sunlight, for example, will
cause its heat-sensing diode to read the room temperature higher than it actually is; if in THERMOSTAT mode, it may not
turn ON the appliance even if the ambient ROOM temperature is below the SET temperature.
COMMUNICATION – SAFETY – TRANSMITTER – (C/S – TX)
This SKYTECH remote control has a COMMUNICATION –SAFETY function built into its software. It provides an extra
margin of safety when the TRANSMITTER is out of the normal 20-foot operating range of the receiver.
The COMMUNICATION – SAFETY feature operates in the following manner, in all OPERATING MODES – Manual ON
and THERMO.
At all times and in all OPERATING MODES, the wall transmitter sends an RF signal every fifteen (15) minutes, to the
receiver, Should the receiver NOT receive a transmitter signal every 15 minutes, the IC software, in the RECEIVER, will
begin a 2-HOUR (120-minute) countdown timing function. If during this 2-hour period, the receiver does not receive a
signal from the wall transmitter, the receiver will shut down the appliance being controlled by the receiver. The
RECEIVER will then emit a series of rapid “beeps” for a period of 10 seconds. Then after 10 seconds of rapid beeping,
the RECEIVER will continue to emit a single “beep” every 4 seconds until the ON button on the wall transmitter is pressed
to reset the receiver. The intermittent 4 second beeping will go on for as long as the receiver’s batteries last which could
be in excess of one year.
To “reset” the RECEIVER and operate the appliance, you must press ON button on the wall transmitter. The flame icon
must be display on the LCD screen. By turning the system to ON, the COMMUNICATION -SAFETY operation is
overridden and the system will return to normal operation depending on the MODE selected at the wall transmitter. The
COMMUNICATION – SAFETY feature will reactivate if the transmitter’s batteries fail or be removed.
SETTING THERMOSTAT OPERATION
1. If the TS-R-2A is in the thermostat mode the word (SET) will appear
on the LCD screen.
2. When the SET button is pressed the temperature digits will begin to
flash.
3. While the temperature digits are flashing use the ON button to
increase the set temperature or use the OFF button to decrease the
set temperature to your desired temperature.
4. When the desired temperature setting is reached press the SET
button, again and the word SET will appear on the LCD screen and
now the thermostat will automatically send an ON or OFF signal to
the appliance.
5. To disengage the thermostat mode push the OFF button or push
and hold the SET button until (2) dashes appear on the LCD screen.
When you release the SET button this will disengage the thermostat
mode and the word SET will disappear from the LCD screen.
