STEP 6
Adjust System On-Length, Clock Display, As
Required
The thermostat on-length is factory-set for
a warm air, gas or oil heating system. If you are
installing it on another type of system, the on-
length must be adjusted accordingly by setting
screws 1A and 1B on the back of the thermo-
stat, using the heating system table in the
figure as a guide. The on-length should be
optimized with the type of system to minimize
If on-length screws 1A,1B are adjusted
to match this system:
electric warm air
gas/oil warm air
hot water or high efficiency
room temperature swings. Setting the screw out
one turn means turning the screw approxi-
mately 360°, or about one complete turn.
In the rare event that you want a longer on-
length, you may readjust the screws as follows,
but be aware that you may be increasing room
temperature swings at the same time.
For longer on-length, readjust
screws 1A,1B to match this system:
gas/oil warm air
hot water or high efficiency
gravity air/water
