SETTING AND CHECKOUT
Temperature Setting
Move the temperature setting lever to the desired
setpoint on the thermostat scaleplate. See Fig. 1 or 2.
Temperature is controlled to that point. On positive Off
models, the control circuit is broken when the lever is
moved to the extreme lowest end setting of the
temperature scale.
Heat Anticipator Setting (T810D)
IMPORTANT
1. Use this thermostat only with controls that have
current ratings equal to (or within) the rating of
the heat anticipator.
2. The T810D Thermostat is equipped with an
adjustable heat anticipator and operates
correctly only if this heater is adjusted to match
the current draw of the primary valve or relay.
3. Do not use the T810 Thermostat on
Powerpile® (millivolt) Systems. Use the TS810
Thermostat that is designed for use on
Powerpile® (millivolt) Systems.
The T810D features an adjustable heat anticipator rated
from either 0.18A to 0.8A or 0.32A to 1.2A at 30 Vac
(depending on model). This heat anticipator must be
adjusted to match the current draw of the primary control
for optimum thermostat performance. The rating of the
primary control is stamped on the control nameplate. To
adjust, move the anticipator indicator lever to correspond
to the control rating.
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 in the direction of
the longer arrows, but not more than one-half
scale marking at a time. To shorten burner-on
time, move indicator in the opposite direction.
