KTC-E Series Dual Purpose Thermostat

One Thermostat for Heating and Cooling

The KTC-E series is a dual purpose temperature controller that integrates normally closed and normally open contacts in a single unit. The NC contact (red dial, terminals 11-12) regulates a heater; the NO contact (blue dial, terminals 23-24) regulates a filter fan or switches a signal device. The two circuits are set and controlled independently with two dials.

  • Stable independent control of heating and cooling

  • Easy to operate, DIN-rail mounting

  • Insulating plastic casing to UL94 V-0, light grey, IP20

  • Long service life > 100,000 cycles
