Adjusting The Temperature Setting - Lightstat TG Series Installation And Operation Manual

Adjusting (optional) night setback setting:
Your Lightstat may come from the factory with a fixed night setback. That means when your
Lightstat thermostat is in the Setback mode, it will automatically set the heating/cooling back
a predetermined number of degrees from the comfort slide setting. If your model has setback
options, there will be a night setback switch on the back or in the lower right hand corner of
the thermostat. Choosing less setback may be more comfortable, but will offer less energy
conservation and savings. See page 11 for more detail on DIP switch settings and setback
features.
Note: When the green setback light goes on, the display will briefly flash showing the night
setback temperature. When the green setback light turns off, the display will flash showing the
comfort slide setting temperature.
Some thermostats may be equipped with a "slide sensitive" setback. (refer to model spe-
cific features to know if your thermostat has this functionality). If the temperature slide is not
moved for an amount of time specified by the customer (and preprogrammed at the factory),
then the thermostat is in setback. To bring the thermostat out of setback, simpley move the
temperature slide.
Note: Typically, moving the temperature slide will show the current thermostat setpoint. For
slide sensitive setback models, the setback setpoint cannot be viewed on the dsiplay because
touching the slide will bring the thermostat out of setback.

Adjusting the temperature setting:

Note: Any time the comfort slide is moved, the display will illuminate and the flashing
number indicates the current setpoint temperature.
1. Make sure the system power is ON.
2. Move the thermostat power switch to the ON position.
3. Adjust the comfort slide either up or down until the flashing number reaches the desired
setting.
4. Once you have stopped moving the comfort slide the display will change from a flashing
display to a steady display. A steady display indicates actual room temperature.
5. A steady dot in the upper right corner of the display will indicate if heating/cooling
system is ON.
Flashing dot indicates time delay
Note: There is a minimum run time of
the heating/cooling turns on to prevent short cycling. Once
the heating/cooling turns off, it will remain off for at least
45 seconds.
