danfoss

Hi Everyone, I have a Danfoss thermostat, unfortunately I am not sure of the specific type but I think it might be either an RMT 230 or RMT 230T. Photos attached. A door was heavily slammed several times on the thermostat during a rather crazy playtime. When I realised what was happening I...

Hi, I'm new here, and I'm new to central heating, but I'm keen to learn. I'm still working my way around the house trying to understand the current setup, and how it works. My aim is to replace the 2 Danfoss controllers (and sensor) with a smart control setup, such as Wiser or Tado, or even...

Hi Following a faulty actuator on a Sunvic 3 port value SDMV2304, I was advised that a compatible replacement actuator is the Danfoss HSA3 (also backed up by http://www.seered.co.uk/sunvic_low_res_catalogue.pdf - see page 18). However the Danfoss HSA3 only seems moves the spindle through 90...

I am trying to swap a danfoss icon thermostat that connect to my wiring center to another that has zigbee support. I tried t wire it up but at first it seems to power up although when trying to put LOAD as in starting to heat the wiring center doesn't detect anything and is not opening the...

Hi all, I currently have installed a Danfoss FP715Si (TP9000) 2-channel CH/HW programmer, but the factory-set clock is entirely wrong and it is just getting old. So it is time to replace it with something more modern. Ideally, I would like to be able to replace it with something that can reuse...

Hello, I'm looking to replace two Danfoss TP5000-m's with two TPOne-M's, and want to check the wiring. My system has a combi boiler with two heating zones (living room and rest of house) each controlled with a separate TP-5000M. The hot water is not controlled by the TP5000's. There is also...

I was hoping someone can tell me how to change the thermostat so we can programme six events per day instead of four? I have tried installer advanced programming but there isn't an option 40 when I scroll through. I would be very grateful for any ideas. I believe it's an old thermostat from...

Hi all i have a danfoss heating controller if that’s the correct term. It controls my oil heating and thermostats for each zone, it also should engage the pump for my back boiler when it’s thermostat gets to temp but it doesn’t seem to be getting any power.

Does anyone know what's inside a Danfoss TP2 and what voltage it works at? My guess is that it's just a thermistor. Also wondering if the programmer supplies it with high/low voltage (dc or ac?) . I've used Arduinos for Internet control of various sensors in the home, so if I knew the...

My FP715Si 230Vac programmer has died. I’m tempted to try another brand as the FP715Si has only lasted 2 months and Danfoss customer service was less than helpful. However, the easy option is to replace with the same unit then I won’t have to change the wall plate. Unless, of course, there are...

Hi, this is my first post, so pardon my ignorance. I've not been too long at this new bungalow for my parents, there is a Danfoss Randall 4033 timer for Hot Water and Heating (click the link for pictures: https://drive.google.com/drive/folders/1zECdyqCUI5sXfGqKD2XgW1zp8M-1zDLu?usp=sharing). It...

Downstairs we have a wireless Danfoss TP500Si thermostat which talks to the Danfoss RX1 single channel receiver also attached to the unit. There is...

Does anybody know how to check a Danfoss RX1-S? I have a CET-2000B-RF with a CS2 Tank Sensor attached, it used to work fine in controlling the hot water The indication on the CET-2000B-Rf Transmitter (I have replaced the batteries in this unit) is showing wi-fi connected and calling for hot...

I have been spending a lot of time at home (due to the coronavirus epidemic), and I decided to take the plunge, learn something new and replaced my Danfoss TP9000 with a nest thermostat 3rd generation. After reading a lot of forum and posts online I was pretty confident that it would be easy...

Hi all Bought myself an early Xmas pressie and will be swapping out an old Danfoss 102 with a single channel Hive. I’m no expert, so could I please ask for a logic check on the wiring. L / N / E & Common I’m ok with. It’s the black wire - Danfoss position #1 that I’m looking for - I think...
