I have recently obtained the new Hive Mini system to replace my current ESI based three Zone (Ch1, CH2, HW) system.
I am looking for a little help on the electrical side which i think i have almost got, but there are a couple of wires I’m unsure on (everything seems to head to the main 3-zone ESI programmer), this differs from other posts for a ESI in a Redrow home (and/or they had no actual responses with answers - hence my post.
Current i have the following installed;
ESI3427B Programmer
ESI ESRTERFW Thermostats (x2)
Currently I believe that the wires in the ESI Programmer are a near straight switchover;
N (4 Cables)
L (4 cables)
3 to 3 (HW ON)
4 top 4 (CH1 ON)
I’m not sure about cable 6 though which is CH2 (upstairs CH)
I have noticed that the Cable [4] in the programmer is a dif colour to that in the thermostat connection, so i assume this gone up to the electrical box on the hot water tank?
The upstairs thermostat also slightly confuses me, as it has a N, L 1,2,3
Which I think is straight swap but wouldn’t the [3] go to the downstairs programmer which goes nowhere?
