Seperating hot water/heating by programme

Thanks to Wellinka have sorted timer issues re heating off periods so thanks for that.
Have a problem seperating the hot water/heating with the CM921 and a Baxi duo tec 28 He. Can only get hot water when heating programmed on so nothing during night if needed. Any useful suggestions appreciated please.

SOURCE: Honeywell ST6400C programmer doesn't switch off

Since you have three on/off timing modes could there be an overlap in the times?
The wires in the unit might be crossed. (don't always assume the contractor who wired maintained the correct colors , I have a friend who blew out a heating pipe because when a replacement motor valve was installed it was never wired right and the plumber assumed the colors were correct so no overtemp shutoff created steam in PVC pipes, OPPS)
There fore maybe one is still coming on. Do you have more than one heating zone? IF so see below

I guess the main question is why manually turn it off? why not use the program.

I will assume your heat is know as forced hot water heating. My house is multizoned however when the zone calling for heat turns off (zone valve closes) I installed a bypass valve in the lowest zone in the house, and reduced the circulator low shut off temp to 130 F which means even though the heat isn't on my circulator will continue to run dumping this excess heat in the lowest part of house to rise through house. (the spring loaded water valve allows the heated water to flow into this zone )We do have two thermistats. And even though the lowest one is not calling for heat the radiators are hot when the excess is dumped into this zone. So investigate and see if your system might be similar. (multizone).

Investigate your wiring, reprogram, replace any battery backup.

SOURCE: loss of temperature control

Is the heater staying on all the time? Most likely cause of themostat trouble is the sensor. Try to find it and measure its resistance at different temps to verify the trouble.

Just bought a house and it has a grundfos timer/pump attached at the hot water tank. I have no hot water and the timer doesn't turn (as I've seen other timers do). Is it supposed to turn so that the...


Grundfos is a sealed unit and not a repairable item.
The timer dial should turn.
And pins located around dial control ON-OFF functions as timer dial rotates.

Does the receptacle have power?
If receptacle has power, and Grundfos is not working, then it is broken.
Grundfos manuals for UP series pumps do not show breakdown or parts list of any kind.
http://www.us.grundfos.com/web/download.nsf/Pages

Bigger question:
Why don't you have hot water?
Is water heater functioning?
Water heater is a separate appliance from Grundfos pump.
Grundfos pump circulates hot water from tank into the lines so there is no waiting for hot water ... but hot water heater should still make hot water.

Add a comment about water heater if that is also a problem.
You could have 2 problems, and water heater is main issue.
