KTBSB-113.500
Room thermostat, heating/cooling, surface-mounted, 230 VAC, 3-stage fan output
“Heating/cooling” air conditioning controller with fan output and heating/cooling changeover switch for controlling fan coil units or partial air conditioning systems in a 4-pipe system for hotel, residential and commercial premises. The KTBSB-113.500 has 3 switches with which the controller is put into operation, the “heating”, “cooling” or “ventilation” function and the fan stage are selected. The operation of the controller and the active cooling or heating are indicated by lamps. The setting range can be limited mechanically under the knob with the setting flags. Surface/wall mounting or by means of adapter plate on flush-mounted box.
