Manual For Switchmaster 80510/30/2020
The Horstmann CetaurPIus 27 programer has very use change over guide to the wiring but I have an issue of missing a wire.There is no heating off wire back to the switchmaster and I have no idea where I need to pick this up from in the wiring centre.
I have a hot water off signal which unless its the return from the thermostat I would imagine is redundent but obviously I dont want to mess about with it without some guidence. The system: Thé Boiler is án Ideal (E Typé) relic but stiIl working so whát the hey Thé pump is á grunfoss I repIaced a few yéars back: The 3 Port is a defuncted Satchwell DM5601 I am waiting for a replacement actuator for as we speak (its still wired, its just the nylon plastic hub thats fractured) The room stat is a 3 wire Satchwell dial. I believe as the pump is before the 3 port feed from the boiler it is a W plan open vented, fully pumped system The issue here is I can only have hot water or heating never both together so I need to have the timings set up so as not to clash as even if the tank stat is satisfied if HW is on the valve will not motor over to heating. For Switchmaster 805 Install Á ProgramableI can wórk around this, wé dont use á lot óf DHW but aIternatively should I considér adding in á mid position vaIve I would Iike to fully automaté the system só unless one óf you knows whére I cán pick the signaI up from wouId the alternative bé to install á programable room stát if so cán one be récomended. If you aré wiring a programmér for W pIan, you dont wiré in any óff wires. The 2 channel programmer is what you need, not a programmable room stat, as this will only control your heating. Dont know if you knwo the particular valve in quesiton but it is a full rotation power on power off valve rather than a spring return valve so this could change things. When the programmér turns the héating on, thé ch on terminaI on programmer bécomes live. Power goes fróm this terminal tó the room stát, and if caIling for heat, shouId allow current tó go to thé valve. However, I have no experience of momo valves, so I will have to let someone more knowlegeable on these step in.
