The Polypipe UH4ZW can be used in conjunction with our mains thermostats. The UH4ZW is also ideally suited for underfloor heating. When used for under-floor heating an option is available to use zone 4 for conventional radiator control.
The UH4ZW can be used to control any actuator or valve which requires a 230v AC signal. At the same time the UH4 offers the ability to operate a boiler or other heat source through a volt free output.
- The UH4 provides central switching of up to 4 zone actuators
- Output for a hot water cylinder and the system boiler and pump
- Neon Indication
- Din Rail Mounting
