    Programmable thermostat for Vaillant ecotec Pro 28

    The problem with you is that you did not comprehend my explanations and problem but instead blabbing about your own solution which you think I should accept. OK let me spell it out in simple words for you.... I wanted to replace the programmable thermostat with the simple Timer switch that...

    Programmable thermostat for Vaillant ecotec Pro 28

    Thanks... as @mikely answered it, I have ordered the same Grasslin FM/1 Digi 20 just waiting for it to be delivered... I would need bit of guidance to remove the Honeywell CM921 Relay and fit that one instead.

    1. Why aren't you bothered about the temperature? Because I can control the radiator temperature from the boiler settings when it is on. 2. Do you have a room thermostat? I have 5 rooms, 1 kitchen, two halls and two toilets.. I would need 10 thermostats to control individual zones...

    Yes I have read the instructions and there are TOTAL 6 settings so no it does not do what I want. If you mean because when setting 2 is ON it automatically OFF setting 1.. that is just a word play ;) If it was 6 On and 6 Off then yes I could have use it as I want to. See these photos below...

    Sorry mate It was joke. Just to clear, You only made a useless statement about how good are Honeywell controls. there was no advice and no positive input from you like the rest of the helpers... If you are easily offended you should be considerate about others too or atleast smile back.

    iPhones are top of the range. I have bought one online and the next day I wanted to smash it on the floor. returned it the next day and got myself a Android Sony ARC S instead. Now I have the exact same feeling about this Honeywell CM921. ;)

    Programmable thermostat for Vaillant ecotec Pro 28

    Thanks guys for your inputs. I have to clarify that I only want a Time controlled ON/OFF timer switch that simply On and off the boiler. I am not bothered about Temperature controlled programmer, Also I think it is only effective if you have thermostat in every room in a house and I only have...

    Hello There 3 settings for ON and 3 for OFF also the same on CM927. I do not want 20 settings but only 6 or 7. Honeywell may be top of the range but it is not good to me if it can not do what I need. I need to setup this following timer 1- ON 00:00 OFF 02:00 2- ON 05:00 OFF 08:00...
