Boiler Temperature Controller
When the water temperature reaches setpoint, the
controller ends the heating cycle. When the water
temperature drops below the setpoint minus the
differential, the control restarts a heat cycle to re-heat the
tank of water.
If the water temperature exceeds the max allowed
temperature, the control enters a manual reset lockout
state. For models that have reset capability, press any on-
board button (when present), cycle power, or use the local
(“rSt”) to reset.
CHECKOUT
Put the system into operation and observe operation
through at least one complete cycle to make sure that the
controller operates properly. See Troubleshooting section
to assist in determining system operation.
LOCATION AND MOUNTING
Sensing Bulb(s)
The boiler manufacturer usually provides a tapping for the
sensing bulb at a point where average water temperature
can be measured. See Fig. 8. Follow the boiler
manufacturer instructions.
The sensing bulb can be installed in an immersion well.
Wells and fittings must be ordered separately. See 68-
0040.
When an immersion well is used, the sensor should fit
snugly and should touch the bottom of the well for best
temperature response. Use heat-conductive compound
(Honeywell part no. 107408) to fill the space between the
bulb and the well to improve heat transfer characteristics
(optional). Make sure the sensor is held firmly in the well.
WIRING
IMPORTANT:
For maximum trouble free operation, run the
sensor leadwires separately from any other cur-
rent-carrying wires.
All wiring must comply with local codes and ordinances.
Disconnect power supply before beginning wiring.
Connect according to water heater manufacturer
instructions.

control module.
