Commissioning of Standard Control System – One Room/Area

• Set the clockstat to call for heat (a flame symbol will appear on the clockstats screen)
• This will put power to the motorised valve and the manifold pump.
• Once the motorised valve has opened, this in turn will put power to the boiler and boiler pump
• Set the mixer valve to give a flow temperature of 25-30ºC. The system should be left to run at this low temperature until the screed//concrete has dried. It can then be raised to its full operating temperature depending on what type of floor construction it is.
• Concrete full operating flow temperature is 55ºC.
• Timber joist full operating temperature is 60ºC.
• Ensure the flow rates have been correctly set the the individual circuits on the manifold
• Check the correct operation of the  Radiator and/or the DHW circuits and that each of these systems can independently bring on the boiler and boiler pump.
• Set the clockstats two temperature settings. The lower one to 16ºC (night setback) and the higher one to 21ºC. These settings can be altered to suit the clients own preferences.
• Set the times on the clockstat, bring the system on (high temp setting) two hours before they want the house up to temperature and switch it to its low temp setting two hours before they retire at night.
• Once the floor has cured (normally 2-3 weeks at low temperature) the 3 port mixer can be set to its correct operating temperature.
• For most of the heating season this temperature can be reduced by up to 20°C depending on the outside air temperature.  This will aid overall comfort levels and increase the economy of your floor heating system.  Thus typical settings are:- Going into heating season set mixer to 30°C - 40°C.  During the coldest spell set mixer to maximum for floor construction.  Coming out of heating season set mixer to 30°C - 40°C.
