Installing Hive - Vokera

garyh3

Hi Just purchased Hive + Hotwater Self install.

Before I install just wanted to ask a few questions

House Built in 2004 Boiler is a Vokera 35HE with a built in analog timer with 15min switches on it. Single Zone system

There is a thermostat in the hall docent seem to do much except switch motorised valve upstairs for hot water only or Heating + hotwater. dosent call for heat when you turn up the thermostat.

Looking at boiler I have found the PCB and with me multi meter found The Permanent live + neutral also found the switched Live for Boiler on /off

Also found the Switched lived from the thermostat to turn the moterised valve on and off.

So questions

Do I just disconnect the Wires for the old Thermostats at both ends and then put a cover plate over or the New Hive

Do I disconnect the cables on the Timer on the boiler also ?

Then how do I wire up the hive Ill need to run a six core cable ?

the diagram has
N
L
HW Off
Heating Off
HW on
Heating on

any help appreciated

So been thinking

Do I just Need
N - Connect N
L - Permanent Live
HW Off - no wires
Heating Off - no wires
HW On Switched Live that was Thermostat ie Valve for turning (valve for HW only or Heating + HW)
Heating ON - Switched Live for Heating

Also do I leave the old Boiler analog Timer connected?

Thanks for any help

To work legally on a gas boiler you must be an RGI.

If your working on the boilers electrics and removing the boiler outer cover, you are doing gas works according the the CER.
