M30×1.5 NC thermal actuator — 24 V DC
A high‑quality, normally‑closed thermal actuator for underfloor heating manifolds and radiator valve bodies with an M30×1.5 thread. The housing uses anti‑flammable PC/ABS, and the threaded collar is stainless steel. Works cleanly with SIMO.io Relay Module control and room thermostats for individual zone heating.
TL;DR
- Thread: M30×1.5 (stainless steel collar)
- Type: Normally closed (NC); opens when powered
- Supply: 24 V DC
- Body: anti‑flammable PC/ABS
- Install helper: red cap spacer holds the valve open for easy mounting; remove after install
- Use with: SIMO.io Relay Modules and thermostats to control room‑by‑room heating
Low‑voltage wiring. Drive the actuator from a suitable 24 V DC supply; switch it with a SIMO.io Relay Module channel. Keep control and mains wiring separate and follow local regulations.
How it works
- NC at rest: with no power applied, the actuator keeps the valve closed.
- Open on power: apply 24 V DC to open the valve and let water flow.
- Zone control: pair each zone with a SIMO.io thermostat; have the thermostat drive a Relay Module output that switches the actuator supply.
Installation
- Leave the red spacer in place to hold the valve open during mounting.
- Screw the actuator onto the M30×1.5 valve body and hand‑tighten.
- Remove the red spacer once mounted; the actuator will now close the valve at rest.
- Wire to a 24 V DC supply routed through a SIMO.io Relay Module channel.
- In the SIMO.io app, bind the zone thermostat to that relay output.
- Test: call for heat; the relay powers the actuator; the valve opens.
Fail‑safe wiring (recommended)
Use the relay’s NC contact. Route the actuator supply through the relay’s normally‑closed (NC) contact. If the Game Changer or control logic fails but 24 V DC supply remains, the relay de‑energizes, NC closes, and the actuator receives power—opening the valve so heating continues. If rooms run too warm, turn down the boiler’s flow temperature until service is restored. Ensure your thermostat logic accounts for the inverted contact (energize = heat off).
