The Comfort Plus can be used to provide control signals to other loads in the application. To do so, connect low voltage control wires to the "COM" and "NC" or the "COM" and "NO" positions of the low voltage terminal block in the electrical compartment of the Comfort Plus system. These contacts are rated for 30 volts, 3 amps maximum.
During off-peak (charge) periods, the contact is closed between "COM" and "NC".
NOTE: Maximum external load should not exceed 60 VA on the system's class II transformer.
If control of external line voltage devices is desired, an Auxiliary Control Relay can be installed.
