Appliance Repair Questions? Ask a Technician for Answers ASAP
Good morning, I see you raised the question some time ago, do you still require assistance?
Hi Ben have you been though the pairing process as it sounds like the RX has lost the paired RF device.
The pairing instructions are as follows:
Step 1. TP7000-RF - Press & hold recessed LEARN button (using a sharp non-metallic object, i.e. bic biro top) for 3 seconds (Fig.20) The thermostat now transmits a continuous signal which contains its unique identity for 5 minutes.
Step 2. RX1 - Press and hold buttons PROG & CH1 until green light flashes. The receiver has now learnt the unique transmission code of the thermostat
Step 3. RX2 / RX3 (if applicable) - For RX2 or RX3 repeat steps 1 & 2 for each thermostat and each corresponding channel
Step 4. TP7000-RF - Press LEARN again to stop TP7000-RF sending signal
No point getting a plumber out if your able to turn the boiler on and off using the manual override, it will 100% be due to a faulty TX or RX.
So as you have already replaced the RX, it has to be the TX, should you still not get them working it maybe the two are no longer compatible or something is causing an issue with the signal, in which case put them next to each other and try and pair them again.
Let me know how you get on.
Will await to hear back from you, at least you know its nothing to do with the boiler.
If that fails, I would be inclined to return both your RX and TX and get a better brand such as Honeywell which comes in a kit.
