  Giacomini R478 Underfloor Heating Thermal Actuator – Normally Open 2 Wire 230 v

  Quick View £18.95 
  Giacomini Hep2o R478 Underfloor Heating Thermal Actuator 230v 2 wire R478V The actuators of the R478 series are normally open (NA). They allow them hydraulic supply of the circuits when there is no voltage and they have a cable with two conductor for the connection to room thermostats or adjustment regulators. The R478M version has a stroke end micro-switch for driving circulators or zone valves. The R478V version has varistor for installation on places where the network voltage undergoes sudden changes that could damage the electronic components. The R478MV version has either varistor or stroke end micro-switch. In radiant panel heating and cooling systems, the normally open electrical actuators are to be preferred as they are not supplied for most of the time involving a sensible electric energy saving. Description In order to allow an optimal control of the room temperature, combining the energy saving with a high comfort, the use of electrical actuators on distribution manifolds, on radiator valves with thermostatic option, or on fancoil valves is advisable. The series of R478 electrical actuators is characterised by an absolute quiet operation, long lasting lifetime as it has no mechanism subjected to wear and a sufficiently slow closing to prevent from water hammer phenomenon. The operation mechanism is made of wax bulbs controlled by low consumption electrical PTC (Positive Temperature Coefficient).

  Heatmiser UH8-RF 8 Zone Wireless Wiring Centre

  Quick View £95.99 
  The Heatmiser UH8-RF is a 8 Zone wireless wiring centre designed to work with the Heatmiser Slimline-RF, Touch-RF and neoAir Thermostats. The Heatmiser UH8-RF provides central switching and is therefore ideally situated next to the underfloor heating manifold. 8 zones can be controlled as well as providing an output for a hot water cylinder. On demand from any zone, a 230v output is provided to switch the relevant zone actuators, underfloor heating pump and valve. A volt free connection is supplied for the boiler, making it compatible with almost all types of boilers. The boiler signal can also be sent via RF to the RF Switch, providing the installer a totally wireless solution. Up to 6 actuators can be connected to each zone. An external aerial is available for use when the Heatmiser UH8-RF is being mounted in a metal cupboard or when the wireless signal is restricted. A software option in the thermostat allows you to configure which zones are underfloor heating and which zones are radiators. Radiator zones will not enable the underfloor heating pump, valve and boiler when there is a call for heat. Radiator zones should enable the boiler from the end switch of the valve. Central wiring unit for up to 8 heating zones DIN Rail Mounting Option (DIN Rail not included) Output for underfloor heating valve and pump activated when any thermostat calls for heat Wireless Fail Safe Function Wireless Boiler Link (RF Switch Optional) Works with our Heatmiser Slimline-RF and Heatmiser Touch-RF) Output for multiple radiator zones Output for domestic hot water Output for underfloor heating valve and pump activated when any thermostat calls for heat Actuator outputs: 230 volts Dimensions (LxHxD) 384 mm x 148 mm x 60 mm Warranty:2 Year Direct Manufacturer Warranty
