Danfoss 103 to single channel hive unit

[run3km]

Hi

Im looking for a bit of help. i have a worsterchester greenstar 15ri boiler.
This does my heating. I have a sperate hot water tank with a separate switch to switch on to heat the water when i don't user the boiler in the summer to heat the water.

I have a danfoss 103 single channel unit and honeywell thermostat.

I ordered a dual channel hive unit as i guessed this was the right one and asked for pro install but when the guy came he said he cant install it as it wont work with my wiring system.

He said i should get a single channel unit to run the heating system only and just switch out the danfoss unit.

He also said he has no idea where the wires from my honeywell thermostat go to so i should leave that attached and just put it up to 30 and the hive unit will still work

I have attached a photo of my danfoss wires

I know the white wire in 6 and blue wire in 5 and green/yellow in natural go to to a socket that powers the boiler

There is a red wire that is in 3 that goes straight to 6 and no where else.

The red wire in 1 im guessing goes to the pump and black wire in 5 goes to pump with the wire that is just a wire is going into natural.

how do i wire it all in from danfoss to hive

Thanks for any help

need a lot more information than you have provided, post pics of all controls and the pipes and anything near your HW cylinder so we can see what you have

so if i want hot water in the summer i use the water heater button. in the winter the hot water gets heated up when boiler is on with radiators

the switch beside the danfoss, one white wire goes into the danfoss and is the blue, white and yellow/green

the grey wire in the danfoss goes up the wall

The other white wire that goes up the wall is connected into the socket (im assuming the power for the bolier)

hope this helps a bit

thanks for your help

OK can see what you have now, your HW is heated bt electricity, and your radiators are heated by your Gas boiler, with the cost of energy these days this is not a good \Idea, unless you have an electric shower and only use that, if you simply want a hive to control the heating then that is easy, you need a single channel one,

hi ian

you are correct and i do have an eclectic shower. my hot water can also be heated when the heating is on but when it is off then i need to use the electric switch as pointed out

i do want the hive just to do my heating only as thats the best i can get with my wiring.

my question is then what wires go where from my existing set up on danfoss 103 to the single channel hive unit to get this set up

Thanks again for your reply

Transfer the lives, neutrals and earth connections from Danfoss to Hive, then the link in Danfoss would go from L to 1 (common) and then the remaining wire goes into terminal 3 for heating on

In addition, the old Honeywell T6060 room thermostat should be either set to its maximum setting to prevent it interfering with the operation of the Hive. Or, alternatively, it can be decommissioned and taken out of circuit.

Inside the lid will be a wiring diagram something like this:

Yours doesn't have terminals 5 & 6, but if it's otherwise the same as per the above, the 'Live' is terminal 1, and the 'Switched Live' terminal 3. [There should be a neutral in 2 for it to work properly, but it appears to be missing] To decommission it, moving the wire from terminal 3 and putting it in terminal 1 with the wire already there will take it out of service.

Alternatively, to remove the thermostat completely, trace the thermostat cable back to its origin. Note where the wires going to the thermostat terminals 1 & 2 are connected at their point of origin, then disconnect & remove the old thermostat and cable. A link should then be inserted between the terminals where the two ‘live’ switching wires have just been removed from so that they are electrically connected together to complete the circuit.

There is a possibility that depending upon the plumbing arrangement that is in situ at the moment, in the winter the hot water may now be heated whenever the Danfoss timeswitch is set to be 'on' regardless of whether the room thermostat is calling for heat or not. With the new arrangement because the Hive has both time and temperature control functions in the one unit, the water will only be heated when the Hive is calling for heat.

Top explanation as usual @stem, however I didn’t comment about decommission or setting to max as

He also said he has no idea where the wires from my honeywell thermostat go to so i should leave that attached and just put it up to 30 and the hive unit will still work

amazing guys thank you so much for your help and advice

 

[run3km]

can you please just confirm

the link that is currently in 3 and 6 on danfoss stays as a link on hive unit going from live to 1 common.

or do i take out the link

Thanks

Yes keep the link and as you stated, which is what I wrote in post #6.
