HEATING
Turn down temperature setting to lowest point. If sub-
base is used, move system switch to HEAT position.
Raise temperature setting until heating equipment starts.
This point should be at room temperature as indicated on
the thermometer. Turn back dial slowly. Heating equip-
ment should stop when dial has been turned below room
temperature.
COOLING
CAUTION
1. Do not operate cooling if outdoor temperature
is below 50° F [10° C]. Refer to manufac-
turer recommendations.
2. Allow five-minute off-time after compressor
has been run to avoid compressor damage.
If T87F controls cooling, move system switch (if
used) to call for COOL and lower setting until cooling
equipment starts. Raise setting above room temperature
and cooling system should shut down. Make certain all
equipment responds properly to the thermostat.
