Ultimate convenience - control your thermostat plus three other household devices from a touchtone phone. The CT241-01 Telephone controller has four universal relay outputs (dry contact). Each output operates independently. It connects directly to existing phone lines and is password protected. LEDs show the output status. It can be activated by home/cell phones and is compatible with answering machines. It allows the user to switch from one mode to another (for TH115 series thermostats) or to turn an electric appliance on or off.
