MULTIPLE APPLIANCE INTERLOCKS
To interlock with one additional 24/115 VAC heater add the MAC1E. It
is a stripped down auxiliary board version of the UC1 and is powered by
and communicates with the UC1 through a factory wired whip.
To interlock more than two 24/115 VAC heaters, add the MAC4E for a
total of up to 5 heaters. It is powered by and communicates with the
UC1 through a factory wired whip.
To interlock a millivolt water heater and a 24/115 VAC furnace or boiler,
add the WHKE and MAC1E.
MILLIVOLT INSTALLATIONS
Each millivolt appliance interlocked with the UC1 must have its own
WHKE kit installed. The WHKE Gas Pressure Switch actuates the
Venter through the A - B Dry contacts. The Linear Limit switch disables
the heater in the event of a venting malfunction. IMPORTANT: Each
millivolt appliance interlocked with the UC1 must have its own Linear
Limit spill switch.
