Number of controlled zones can be increased up to 15 zones by connecting CB500X extension modules to the CB500 unit which is equipped with a module system that controls the source of heating and cooling. Each individual zone can be operated by one thermostat. Thermostat which require 230V power supply have to be powered directly from control box. The spring clamps provide quick and convenient wiring connections. The control box is designed to work with NC (normally-closed) type actuators. It is recommended to mount it on a surface or on a DIN rail.
