Giacomini / Hep2o Manifold Thermal Actuator The 4 wire Giacomini R473M actuator is normally closed (NC) 230volt
Giacomini Hep2o Underfloor Thermal Actuator 230v 2 wire R473 N.C.
Quick View £16.95 £20.34 Inc VAT
Giacomini / Hep2o Manifold Thermal Actuator R473 The actuators of the R473 series are normally closed (NC); they allow the hydraulic supply of the circuits in presence of voltage and they have a cable with two conductors for the connection to room thermostats or adjustment regulators. The R473M version has a stroke end micro-switch for driving circulators or zone valves. The R473V version has varistor for installation on places where the network voltage undergoes sudden changes that could damage the electronic components. The R473MV version has either varistor or stroke end micro-switch. These models have a manual block mechanism in opening position to make the assembly on valves easier, and allow maintenance to the electric plant by maintaining the water circulation into the hydraulic system. 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 R473 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).

Giacomini R478 Underfloor Heating Thermal Actuator – Normally Open 2 Wire 230 v
Quick View £18.95 £22.74 Inc VAT
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.
