— Let the system operate through the ammeter for 

at least one minute before taking a reading. 
Record the reading here ______________ .

— Reconnect the W wire to the W terminal.

Move the heat anticipator indicator to match the 
number you recorded in Step 3 or in Step 7.

NOTE:  Hot water and steam systems require you to 

multiply the current rating times 1.3. For elec-
tric heat systems, add the fan relay current, 
usually 0.2A to 0.4A.

Snap the cover ring over the thermostat dial.

8 SET THE TEMPERATURE

Turn the transparent dial until the desired point on 
the setting scale is aligned with the pointer, as shown 
in the illustration.

IMPORTANT:

During a call for heat or cool, an electrical 
spark can be seen through the colored 
decorator cover ring. Do not be alarmed; 
this is normal operation for a mercury 
switch. 

Set Subbase Switch

CAUTION

Equipment Damage Hazard.
Can cause permanent damage to the 
compressor.
Do not rotate the thermostat dial back and forth 
just to observe the electrical spark; observe the 
compressor five-minute minimal-off period.

To operate the heating system, set the subbase 
System switch to Heat. To operate the cooling 
system, set the subbase System switch to Cool. Set 
it to Off if you want neither heating or cooling.

Set the Fan switch to On for continuous fan 
operation or to Auto for fan operation during heating 
or cooling cycles.

9 CHECK OUT THE SYSTEM

Heating

Turn down the temperature setting to the lowest 
point. Move the System switch to Heat. Raise the 
temperature setting above room temperature; the 
heating equipment should start. Lower the 
temperature setting below room temperature; the 
heating system should stop.

Cooling

CAUTION

Equipment Damage Hazard.
Can cause permanent damage to the 
compressor or other equipment.
To avoid possible compressor damage, allow 
the compressor to remain off for five minutes 
before restarting.

To avoid possible equipment damage, do not 
operate cooling when the outside temperature is 
below 50

°

F (10

°

C).

See equipment manufacturer instructions.
