SETTING AND CHECKOUT
Temperature Setting
Move the temperature setting lever to the desired
setpoint on the thermostat scaleplate, see Fig. 1, to
control the temperature to desired point. (On positive
off models, the control circuit is broken when the
lever is moved to the extreme lowest setting of the
temperature scale.)
Heat Anticipator Setting
(Select Models)
IMPORTANT
1. Use this thermostat only with controls that
have current rating equal to (or within) the
rating of the heat anticipator.
2. Setting the heat anticipator allows the
thermostat to maintain accurate temperature
control.
Models with an adjustable heat anticipator should be
adjusted to match the current draw of the primary
control for optimum thermostat performance. To
adjust, move the anticipator indicator lever to
correspond to the control rating. See Fig. 1.
If the setting and current rating are not available, wire
the thermostat into the system, but do not attach it to
the wall. If the thermostat is already mounted, remove
it from the wall, leaving it connected to the system
wiring.
Connect an ammeter of the appropriate range (about
0.0A to 2.0A) between the terminals on the back of the
thermostat. Move the temperature setting lever to a
low setting so the contacts are broken. In cold
weather, it may be necessary to hold the switch so the

controls remain open. Allow the system to operate
through the ammeter for one minute. Adjust the
anticipator to match the meter reading.
NOTE: For best performance, the heat anticipator
can require further adjustment. To lengthen
burner-on time, move the indicator to a
higher number, but not more than one-half
scale marking at a time. To shorten burner-
on time, move the indicator in the opposite
direction.
Cool Anticipator (Select Models)
Models with a cooling anticipator have a 24 Vac to
30 Vac fixed anticipator.
