ABSTRACT:
An ambient room illumination responsive control automatically changes the setting of a thermostat with ambient illumination. A thermostat has a pair of temperature responsive switches connected in series with control leads and a controller to low voltage A.C. power. A bypass relay has contacts connected in parallel with one of said switches. An illuminating sensor has a photoresistor in series with a resistor connected across leads with a common node connected to the gate of a controller rectifier. A capacitor timing unit is connected in one embodiment to produce a pulsed input. The rectifier is connected in series with a winding of the bypass relay and the timing unit across the thermostat leads. The rectifier conducts to open the relay contacts and insert the second switch in circuit. A second relay winding is connected across the control leads in series with a diode and a timing network to reset the relay and close the contacts. The time constants of the two timing circuits where employed insure proper operation of the set and reset branch circuits. A separate remote pulse control may be provided.
