230V Easy-operated Indoor Heating and Cooling Control Temperature Non-programmable Gas Boiler Thermostat
C3 is a push button room thermostat with a clock display, built for hotels and indoor spaces that need heating and cooling control without a programme to learn. The switching side uses an Omron relay rated 8(2)A at 230VAC, which covers boilers, fan coil units and radiator circuits. Sensing is by NTC with a display accuracy of 1 C or better.
