Hi Everyone,
I would really appreciate some help.
Last year we had a new CH/HW system installed, comprising of
Vaillant ecotec plus 637
ACV smart 210 green
Siemens rwb29 controller
Center honeywell wireless room thermostat.
The HW has been working perfectly throughout and the CH worked brilliantly last winter.....
To control the CH system last year we set the controller to CH manual on and used the programable timer to keep the house at a nice temperature. Turned it to manual off over the summer...
This year when I do exactly the same thing the CH comes on but will not turn off with the thermostat. It is a big boiler, so the house starts to resemble a sauna very quickly.
I have changed the batteries on the thermostat....no better... if you up and down the thermostat it does show the wireless signal on the room thermostat and the receiver box light does go on and off...now is the really odd part...
It was due a service and I explained the problem to the engineer, he was a bit stumped, but as he clicked the vaillant into service mode it started to work perfectly again. put the siemens controller onto CH manual on...The boiler would fire and stop according to the thermostat...worked perfectly for 24 hours, but it has now gone back to the same problem and we are either freezing or in the sauna again
Any suggestions would be greatly appreciated.
Sincerely,
Steven
