ST9420C operates as the control hub of the system, and DT92E is free to be positioned anywhere in the living space. Sundial RF² is a registered trademark of Honeywell Inc.ĭT92E and ST9420C both use 2-way communication on an 868MHz radio frequency (RF) band to control the heating and stored hot water system.

See Schematic System Layouts (below) or refer to for full details. Other Honeywell Home products may be required for a complete installation. It operates on 2xAA alkaline batteries, giving a battery life of at least 2 years under typical operating conditions. It requires permanent mains 230Vac power.ġ x DTS92E1020 Wireless digital room thermostat with energy saving ECO function. This pack provides a wireless control solution for adding a wireless room thermostat to an existing Sundial system with wired cylinder thermostat.ġ x ST9420C1008 Wireless enabled 7 day programmer with 2 output control relays for switching boilers, pumps and zone valves in heating systems.

(Don’t just go by the old colours of the old valve.

Generally they are a nightmare to figure out without a solid knowledge of how these systems work)įit the new valve and follow the instructions on how to wire it up. Beware the terminal boxes for electrics in heating systems. Then you should have a permanent live that is switched by the 2 port valve itself that goes off to the boiler and pump.
Remove 2 port valve making a note of the wiring (you should have a switched live from the thermostat to the valve motor. Isolate water supply to heating system (in loft or mains)ĭrain heating system down (find a drain off below the level of the 2 port valve) Turn off all heating components electrically You can manually latch the valve open while you wait for a replacement valve to be fitted.

You can test to see if the valve is stuck by moving the manual arm on the side of the valve. Symptoms of this can be only hot water and no central heating or vice versa. When the motor head goes to move the valve position it burns the head out. Over time the valves can get stuck (especially after a summer of being in one position). If you aren’t sure which part to buy then ask you engineer what make and model you need.īuying 2 port valves online is relatively simple. If you buy the boiler and get the engineer to fix it for you, then you avoid their mark up and save money. What if you’re looking to buy new or replacement components? Most customers find it easier to allow their installation engineer to buy the parts but this is not always the cheapest option. So we’ve had a quick look at how 2 port valves and how s plan systems work. This is ideal if you have an under-floor heating system that you want to control separately. Instead of just having one zone for the hot water cylinder and one for the radiators, you can use another 2 port valve with its own controlling thermostat and power.
The 2 port valve has one live supply to motor it open when called to by the particular service it supplies.Ī great advantage of S plan systems over Y plan systems is the opportunity to have more than two zones. Soon you should feel some hot water in your radiators.
Multiple zone control for more than one hot water cylinder, radiator or under-floor system.Close temperature control on hot water system and heating system.
