The HMUH8RF is an 8 Zone central wiring centre for use with Heatmiser NeoAir thermostats. It can be used to control any actuator or valve which requires a 230v AC signal while at the same time offering the ability to operate a boiler or other heat source through a volt free output with changeover contacts, which gives you both a heat on signal and a heat off signal. Additional outputs designed for use with hot water or underfloor heating systems, are also included as standard. These are the pump and valve outputs which would normally operate a manifold pump or a manifold valve, and the H/W output which is used to send a hot water on and hot water off signal. Any output which is not needed can be ignored. 99 channel numbers are available allowing up to 99 different HMUH8RF wiring centres to be operated in close proximity. With 8 thermostats per wiring centre this gives you up to 792 distinct heating zones. When wiring directly to the heat source is not possible, a radio link is provided to remotely enable a separate receiver, the RF-Switch. Test switches are included for the installation engineer and further options include creepage protection and pump delay.
