Thermostat - OJ - OTN-1991 H11

OTN-1991 H11 is an electronic thermostat for underfloor heating with a built-in relay rated for currents up to 14 A. It is used with a floor temperature sensor. The OTN-1991 H11 scheme provides for the possibility of automatically lowering the floor temperature by 5 ° C at the desired hours, usually at night. To do this, the timer must be connected to the Thermostat via terminal 3. If nighttime temperature reduction is not involved, then terminal 3 remains free. The Thermostat for the underfloor heating OTN-1991 H11 has a protective shutdown circuit that is triggered by an open or short circuit in the temperature sensor circuit.
