The CT241 telephone controller is designed to remotely control up to
four independent loads.
For example, you could connect a sprinkler system, a water heater,
etc. Another example would be to connect an output to the thermo-
stat’s phone interface (which requires a dry contact) to switch from
Comfort mode to Vacation mode and vice versa.
Loads can be activated or deactivated remotely (by telephone) or
manually (on-site).
