SETTING LEVER
Recheck for level positioning, and firmly tighten both
mounting screws.
Make sure you have the current draw anticipator
setting for your system. This is the number you
wrote down in Step 3. If you were unable to find the
current draw for Step 3, this information can be found
printed on the primary control at the furnace. The primary
control is usually a gas valve, zone valve, or a relay or
burner control box with the thermostat wires connected to
it. For electric heat, you need to add the fan relay current,
usually 0.2A to 0.4A.
Set the heat anticipator indicator at the rating printed
on the primary control.
Replace the cover by hooking it over the top of the
thermostat base and pressing the bottom in until it
snaps into place.
CAUTION
To prevent possible damage to the anticipator
(burn out).
Do not set the control too low. Do not allow thermo-
stat wires to short out at the the main control valve
on the furnace.
