Hi,
I have a Vaillant Ecotec Exclusive with Green IQ 835, VRC700, weather composition, VR920, Ambisense VR50 and V51. I followed the advice of different posts, especially https://www.diynot.com/diy/threads/vaillant-system-gremlins.541433/
However, I still have several problems:
===================================
So far I tried the following:
===================================
My aim
=====================================
I don’t mind having the non-existing zone(s) in the app, as long as they are not causing the problems. But I like to have the boiler not firing when the Ambisense does not request heat, during the set back periode at the night.
My system and settings in detail:
===============================
Settings on the VRC700f
===========================
Adaptive curve = Yes.
Configure heat circ = Zone 1 (Change to all does not help)
System diagram = 1
Type of circuit = Heating
Max limit outside temp = 17
Heating curve = 1.
Min temp = 25C
Max temp = 60C
Auto off mode = Eco
Room temp modulation = None
Zone 1 activated = yes
Day temp heating = 20.5C
Set-back temp heat = 15C
Zone 1 assignment = VRC700 (I changed this to none, makes no difference)
Cylinder = Inactive
HW temp to 60C.
Ch pump overrun time = 60 min

However, I still have several problems:
===================================
- In the VRC700 app, two zones are shown, despite having only one, plus a non-existing ventilation system. All zones have ventilation have some weird time schedule, which is not possible to change.
- (Only!) During the night the boiler cycles, hot water comfort mode is off. The VRC700f switches to day mode requesting 21C, despite no room requiring heat at this time,
So far I tried the following:
===================================
- Reset the VRC700f
- Reseted all Ambisense heads and VR51
- Changed setting of room temp modulation
- Connected a homeassistant hub with multimatic plugin to a have a history of all temperature and heating request. I use the homeassisstant exclusively for monitoring and connecting it has not changed the behaviour. No heating request is shown during the cycling at night.

My system and settings in detail:
===============================
- One heating circuit, flow and return for each rad
- 9 rads in total, 7 with Ambisense, 2 with standard TRV on lower setting, hence these two are mostly off
- 4 of the 7 Ambisense equipped rads joints with a VR51 in the living room
- Location of the VRC700f currently living room
- Water pressure is about 1.3bar
- No cylinder, only DHW
