The wiring centre is where all the wiring for a under floor heating system meets. It is powered by a 230v fused-spur supply and coordinates the signals received from each of the heating thermostats. When each thermostat calls for heat in any one of the heating zones the following happens: The zone valve on the primary heating circuit opens (only on the first thermostat calling for heat – it then remains open until the last thermostat reaches temperature) The manifold pump is fired, maintaining the flow rate around the UFH pipe work loops Sends an ‘enable’ signal back to the boiler to activate it, if it is not already firing On market, there are two types: Wired wiring centre & wireless wiring centre. The main different is how thermostats at each zone connect to wiring centre. For wired wiring centre, the heating thermostats at each rooms are connected to wiring centre by cables, and get power from wiring centre also. For wireless wiring centre, zone thermostats are RF wireless communicate with wiring centre. Compared with wired version, wireless wiring centre is much convenient on those house without cable installed. We supply both wired and wireless wiring centres for 230v, 12v, and also wired digital thermostat, rf wireless thermostat. They are suitable for 1 to 16 heating zones. For some application needs, WIFI, Opentherm, Modbus function can be combined into wiring centre. If you have more information about wiring centre, please email to info@etopcontrols.com. 

When setting up the HR-02 wireless wiring centre for heat pump heating system, two critical parameters need attention: Valve Type Selection and Delay Time Setting. Proper configuration of these settings is essential for optimal system performance. 1. Valve Type Selection The actuator type can be configured to either Normally Open (NO) or Normally Closed (NC). The choice determines how the actuators respond when the heating system is activated. Choosing the wrong valve type can lead to system malfunctions, such as the wiring centre failing to operate correctly. The HR-02 wiring centre allows for easy selection between NO and NC configurations, ensuring that users can adjust settings according to their specific needs without concern.   2. Delay Time Setting The delay time setting for the pump and boiler can be adjusted between 0 to 6 minutes using a bridge jumper. This feature is crucial as it helps mitigate issues related to short cycling, where the pump and boiler frequently turn on and off in quick succession. Short cycling can lead to increased wear and tear on these components, potentially shortening their lifespan.   The proper delay time can ensure the pump and boiler have adequate time to stabilize before being activated again to protect the equipment and keep the room heating control without reducing unnecessary energy consumption.
