Vaillant Thermostat Questions

[systematic92]

Dear Experts,

I own a Vaillant EcoTec 831 Boiler and was wondering what the best thermostat is to use alongside this?

I stupidly bought a VRT392 device, which I afterwards learned is a hard wired device.

For ease of use, I was looking for a wireless device and I am assuming the VRT392F is the model I need. However, before I take the plunge in buying one, is there something better that you know of?

Last question - If the 392F is in fact the model I require, do I need to purchase and additional device for the front of the boiler too? I am curious as to what the VRT392F communicates with? Presumably I need something else to plug into the front fascia of the boiler unit for the 2 way communication to occur?

Thank you for your help and please excuse my ignorance on this,

But a sunvic controller and just get your gas safe installer to fit it. You cannot as your not allowed to remove door of boiler as it forms an integral part of the boilers safety system put it back incorrectly and forget needing a stat the morgue is always at 5c
