Cleaning the Control

The control’s exterior can be cleaned using a damp cloth. Moisten the cloth with water and wring out prior to wiping the
control. Do not use solvents or cleaning solutions.

Boiler
If a steam boiler or steam valve is connected to the Boiler
terminals (7 and 8), make sure power to the boiler circuit
is off and install a jumper between the terminals. When the
circuit is powered up, the boiler should fire or the steam
valve should open. If the boiler or steam valve does not turn
on, refer to any installation or troubleshooting information
supplied with the boiler or steam valve. If the boiler or
steam valve operates properly, disconnect the power and
remove the jumper.

Connecting the Control

Make sure all power to the devices and terminal blocks is off,
and remove any remaining jumpers from the terminals.

Reconnect the terminal blocks to the control by carefully
aligning them with their respective headers on the control,
and then pushing the terminal blocks into the headers. The
terminal blocks should snap firmly into place.

Install the supplied safety dividers between the unpowered
sensor inputs and the powered or 115 V (ac) wiring
chambers.

Apply power to the control. The operation of the control
on power up is described in the Sequence of Operation
section of the brochure.
