D Note the tabs on the top inside edge of the ther

mostat base. These fit the slots molded into the top of

the wailplate or subbase.

n Hang thermostat base on wailplate or subbase.

6 MOUNT THE THERMOSTAT—-----------------

! I Insert the two captive mounting screws located in

the bottom corners of the base (Fig. 5).

Q Firmly tighten screws.

7 SET HEAT ANTICIPATOR----------------------

n Make sure you know the current draw (anticipator

setting] for your system. This information can be found

printed on the primary control at the furnace or on the

furnace output/listing label. However, it is good in

stallation practice to physically test the heating primary

current draw before setting the heat anticipator. This is

done by connecting the R and W terminals through a

suitable meter (0-5 A), or with thermostat wire held

through a clamp on meter using multiple loops to mag

nify the field (ten [oops are typically used so meter read

ing can be divided by ten). Physical measurement is

urged, as modern HVAC equipment typically incor

porates multiple control circuit loads, and accurate

anticipator setting prevents poor control and callbacks.

□

Move heat anticipator lever to match the current

draw (Fig. 6), except in single-stage heat pump sys

tems. In these systems, set the anticipator at 1.4 times

the actual current draw to reduce the cycling rate.
