How do I wire a separate pump to receiver unit
I bought the Tado wireless receiver to replace my Horstman 3 channel programmer (+ TRV’s & thermostat).
The current 3 channels are C/H, H/W and (3) a separate pump which is on the hot water return.
So at the moment I can set a separate timer for this pump.
I should also add the the pump cable goes directly in to the Horstman.
Whereas the C/H & H/W cables go firstly into a Honeywell junction box (along with numerous other wires), and then are separated into Live, Neutral & Earth and then go into the Horstman.
Any help greatly appreciated.

Should add that we have 3 phase power supply. Not sure if this make a difference.0

Tado isn’t intended to support hot water circulation pumps. In your situation I’d retain the Horstman programmer to control the circulation pump, but use the Tado wireless receiver to control CH and HW. The CH and HW cables will need to be swapped from the Horstman to the Tado receiver and the receiver will also need a permanent Live and Neutral for its own power.
Your setup is non-standard so you may not get support from Tado for a DIY install. Leaving you to find someone competent to make the necessary wiring changes.
