FAQs
Who should install the Horstmann Secure Z222?
The Horstmann Secure Z222 must be installed by a qualified heating engineer or plumber.
What size pipe does this valve fit?
This is a 22mm valve, suitable for standard 22mm pipework.
Can I control multiple zones with one Z222 valve?
No, the Z222 is a 2-port valve designed for controlling a single zone or circuit. For multiple zones, you would need multiple valves.
Does this valve come with a thermostat?
No, the Horstmann Secure Z222 is the motorised valve itself. It requires a separate thermostat and programmer to operate.
How do I know if my system needs a 2-port valve?
A 2-port valve is typically used when you want to control hot water and/or heating to a specific area independently from other parts of your home.
What is the main function of a motorised valve?
A motorised valve controls the flow of water in your central heating system, opening and closing automatically based on signals from your thermostat or programmer, to manage heating and hot water delivery.
Troubleshooting
Valve is noisy
Slight humming during operation is normal. Persistent grinding or loud noises may indicate an issue and require inspection by a qualified engineer.
No hot water or heating to the zone
Check that the thermostat and programmer are set correctly and calling for heat. Verify electrical connections to the valve. If problems persist, contact a qualified engineer.
Valve does not open or close
Ensure the system has power. Check wiring connections. If the actuator is not responding, it may need replacement by a qualified engineer.

Setup, Compatibility & Care
Setup: The Horstmann Secure Z222 *must* be installed by a qualified heating engineer. This is crucial due to its integration into the central heating system and electrical connections. The engineer will ensure it is correctly plumbed into the 22mm pipework and wired to the heating control system (programmer/thermostat).
Compatibility: This valve is designed for standard 22mm copper or plastic pipework commonly found in domestic central heating systems. It is compatible with most standard room thermostats and programmers that provide an electrical signal to operate a motorised valve.
Care: Generally, this valve requires no user maintenance. Its internal components are sealed. If you notice any unusual noises or performance issues, do not attempt to service it yourself; contact a qualified engineer. Ensure the area around the valve is kept clear of obstructions.
