Thank you for your replies. I'm sorry about all the posts, I'm struggling to find the perfect one. I have considered a lot but only bought Honeywell dt90e, which is a tpi one and it was a nightmare. Turning on and off all the time, not enough time to even cycle the water through the system. I...

Hello, I would like to swap my old Honeywell thermostat for a nest e thermostat. I have two wires connected to combi boiler Ariston e combi evo. Do you think, if I connect one wire to c and the other to no on the nest, it will work? Also I'm not sure how it controls temperature. Is it one of...

Hello, can anybody please help me with how to set the Auto button on Ariston E-combi evo boiler? I know I can press it to activate it. But if I press +/- on the heating side(right), there's a scale with zero going to plus and minus. Does anybody know how it works and if it needs to be...

Thank you, so it is a bit more complicated then. Probably not much can be done about it as it is a rented property I guess.

Thank you, I might try that. Yeah, all on exterior walls. I'm not sure about rendering. Front of the house is stones and the side seems smooth.

Hello, does anybody know what these spots or stains on the walls are please? Is it some kind of mould? What's causing it and how to get rid of it? I guess it might be hard to see they're not dark looks as it is wet but it's round in shape, I'm not sure but doubt that water marks would look like...

Thank you, haven't done it yet. I'm back at work foe four days now so hopefully sometime next week I'll have a go at it. Yesterday I read somewhere that live should go into com and the other one into no. Exactly what you suggest, so in my case it would be blue into com and brown into no. So I'm...

Hello, I have a mechanical Honeywell thermostat and would like to change it for Flomasta 6259g programmable wired battery operated thermostat. It is connected with two wires to a condensing combi boiler. Could somebody help me how to wire it please. I have two wires brown and blue. Is it okay...

Hello, you're a lifesaver. Thank you very much. There is one more thing I'm not sure about. In the manual there is a setting for Heat Control Mode with options on/off load compensation and on/off standard. I would guess that the on/off standard probably works like a normal hysteresis thermostat...

Hello, I would like to swap my old Honeywell thermostat for Danfoss TP5001B. Unfortunately I'm no expert and am unsure about the wiring. The Honeywell thermostat is connected with two wires. Could somebody advise me whether I can use the Danfoss with 2 wires and how to wire it? Thank you.

Thank you all for your replies. So it seems it might just need more time (I'm not the most patient person but will have to get over myself this time). You're right about the clicking, a lot of people complain about it. Read somewhere it might depend on the wall type, different materials make it...

I think it is calling for heat, the flame symbol comes on and boiler kicks in. Hoping its just the learning period. It probably won't get much of a chance to learn untill winter now . I guess time will tell.

Every time I set a temperature it overshoot 0.5 degree and keeps calling for heat to keep it at 21.5 instead of 21 degree for example. So when I get too warm I turn it down and then when the temperature drops to half degree above my new target temperature it starts calling for heat again. Is...

Thank you for your replies. But does anybody know if it is suppose to stop calling for heat after it reaches the set temperature? And if it overshoots then just stop and wait for the temperature to drop? I will give it more time to settle, just wanted know whether I have a potential problem on...

Hi, does anybody have any experience using Honeywell DT90E thermostat? I just got one, connected to Ariston combi boiler which has auto function for self-regulating of the water temperature in the radiators. Would it be a good idea to have it activated with this thermostat? I only been using...
