Use a touchtone phone to heat your cottage or home just in time for your arrival. The CT240-01 Telephone controller has two outputs: one for low voltage output (12 VDC signal) to control an Aube thermostat (TH135-01, TH140-28-01, TH141HC-28), and one for universal relay output (dry contact). Both outputs operate simultaneously. 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 thermostats) or to turn an electric appliance on or off.
