Multiple Heater
Control - Option CL31
and Option CL32
If the heater was ordered with a multiple heater control option, one thermostat
can be used to control multiple heaters. The option will control a maximum of
six Size 400 heaters, a maximum of three Size 800 heaters, or a maximum of
two Size 1200 heaters.
The option includes a 40 VA transformer that replaces the standard transformer
in the ”control” heater and a relay assembly that attaches to the “non-control”
heater. Option CL31 provides for control of two heaters. If control of additional
heaters is desired, Option CL32 which is the relay assembly only, must be
added to each of the “non-control” heaters.
The option packages are shipped separately and include complete instructions
for installation and wiring.
