Question about Honeywell Programmable Thermostat Heater

Open Question

Changed timeclock and system no longer works correctly!

I stupidly changed a Danfoss 4033 timeclock to a Grasslin Q2 , before getting any connection details for the original Danfoss. I have tried to find schematic drawings to suit the various valves and switches but so far I,ve failed . I,ve got two motorised valves one in the HW and one in the CH pipework both spring return and both only two wire i.e Live and Neutral . A cylinder stat with N/O and N/C contacts and a Room stat with N/O and N/C contacts along with the previously mentioned time clock with HW on HW off HTGon HTG off connections . It,s all got a bit frustrating . I know the boiler requires a switched supply as well as a permanant live and the frost stat is connected across these two cables .But I.m stuggling to get it to work without the Aux switches usually within the motorised valves. Can any one help ?

SOURCE: Have a ct87k. Got power at wall. Plug t-stat nothing.switches are both off for gas.

Those normally do not fail, they have a mercury switch in them. However there is a cravat they have to be mounted level and up side up. If that is the way it is mounted then just replace it.

Grasslin Uni 145. Why isn't it working?


In an electromechanical timer such as the one illustrated, you must rotate the dial clockwise (as shown by the arrows on the dial) to reset the time. The "easier" alternative of rotating the dial backwards will destroy it.

Shower valve making banging noise pressure balanced even after changing cartrige


turn hose water off. open facet at lowest level to drain out lines. open a few faucets around the house to let air in. then close everything up. turn water back on. repressurize system by turning some faucets back on. see if it still happens. this is letting air back into any anti-water hammer devices that might be in system. sometimes they loose the air in them that makes them work. this should add air back in. good luck.

Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Grasslin ecosave timer not working


Add a comment and say if the timer worked before and stopped working, or if this is new installation that does not work correctly.
Otherwise the timer expert is guess that the problem is incorrect wiring, defective timer, tripped circuit breaker, or if the clock motor has gotten weak over time, and stopped working.

Or, Contact Grasslin UK:

I have pressed reset on my grasslin qe1 timer and now nothing will work on it


Grasslin qe1 and qe2 manual does not show troubleshoot section.
http://www.grasslin-controls.co.uk/assets/graphics/static/QE1-QE2_GB%20instructions.pdf

1) Remove power to unit and see if it will reset.
2) Press reset and hold button longer
3) Manual says: SLIDE SWITCH MUST ALWAYS BE LEFT IN "RUN PRESET PROGRAMME" OR, "RUN OWN PROGRAMME" POSITION, OTHERWISE THE CLOCK WILL NOT RUN, AND NO SWITCHING WILL OCCUR.
4) Timer has stopped working. I test timers, and they all stop working one day.

It sounds like your hydrostat pump and motor are failing (leaking too much). Seals will not fix this problem. Send me your model numbers for verification and further info.
