The Mini-Wave Control System is capable of
controlling most heaters or heat pumps in the
market today, using thermostatic circuitry of 24VAC
@ 2A or less. Locate your heater on the following
pages and follow the instructions for proper
installation with your Mini-Wave Control Center.
NOTE:
Your Mini-Wave Control System can be
modified to provide a cool-down period for your
heater. Consult your heater owner’s manual for
specifics concerning a cool-down period
requirement.
