Description
NC Thermal Actuator Individual Control for Each Underfloor Heating Circuit
230 V normally-closed electrothermal actuator for controlling individual underfloor heating manifold circuits. Compatible with both Quicksmart Q20 Wireless and Q10 Wired systems.
Closed when unpowered and opens when energised.
Direct integration with Quicksmart controllers.
Designed for manifold installations.
Standard connection for compatible manifold valves.
The component that opens and closes each heating circuit.
In an underfloor heating system, each room can contain one or more heating circuits connected to the manifold.
The thermal actuator is fitted to the manifold valve and receives its command from the controller. When the room requires heat, the actuator opens the associated circuit.
When the target temperature is reached and power is removed, a Normally Closed actuator returns to the closed position.
Closed when no electrical power is applied.
Compatible with Quicksmart Q20 and Q10 controllers.
Stable operation of the manifold valve.
Mechanical actuator travel.
One actuator, two Quicksmart systems
The same NC actuator is used by both the Q20 Wireless and Q10 Wired underfloor heating systems.
Q20 Wireless
The Q20 Controller operates the actuators according to wireless room thermostat demand.
Q10 Wired
The Q10 Controller operates the same 230 V NC actuators using wired room thermostats.
Standard connection
M30 × 1.5 threaded connection for compatible manifold valves.
Protected housing
IP54 protection for manifold-area installation.
Actuation force
Designed to operate compatible manifold valve inserts reliably.
Individual circuit control
Allows each room or zone to open only the circuits that require heat.
From room temperature to the floor circuit
The thermostat decides when heat is needed, the controller manages the zone, and the actuator operates the circuit.
Room Thermostat
Measures room temperature and sends a heating request.
Q20 thermostat →Controller
Identifies the zone and powers the corresponding actuator output.
Q20 Controller →NC Actuator
Receives 230 V and opens the associated manifold valve.
Thermal actuator →Heating Circuit
Water flows only through the circuits that require heat.
Q20 Wireless
Uses wireless room thermostats with the same NC actuators.
Q20 system →Q10 Wired
Uses wired thermostats with the same NC actuators.
Q10 system →Technical specifications
Key specifications and system characteristics for planning a compatible Quicksmart installation.
Control each underfloor heating circuit individually
Use compatible NC thermal actuators with Quicksmart Q20 or Q10 controllers to create true room-by-room heating control.
