The COMPUTHERM Q4Z zone controller can control up to 4 heating zones controlled by a switch-operated thermostat. Each zone can be operated separately or even simultaneously. This makes it possible to always heat only the rooms you just need. The heating system designed in this way greatly increases comfort and also contributes significantly to reducing energy costs. Our COMPUTHERM Wi-Fi thermostats can even be connected to the zone controller, with the help of which a remotely controlled heating system can be created for each zone.

The zone controller controls the boiler at the command of the room thermostats and commands the opening / closing of the heating zone valves (max. 4 zones) associated with the thermostats. Any switch-operated room thermostat with an output relay capacity of 230 V AC, 50 Hz, min. 1 A (0.5 A inductive). The zone controller can be easily connected to any gas boiler with a two-wire room thermostat connection point, regardless of whether they have a 24 V or 230 V control circuit.
