Install SALUS iT800 WiFi smart termostat

I’m looking for a qualified heating engineer to install a SALUS iT800 WiFi Smart Thermostat. I currently have a Vaillant ecoTEC pro gas boiler with an older wireless Honeywell thermostat. The job involves: * Checking compatibility with my existing boiler and wiring. * Removing the old Honeywell receiver and installing the new SALUS receiver. * Setting up the wireless thermostat and WiFi app. * Testing everything to ensure it works correctly. I haven’t purchased the thermostat yet, so I’d like compatibility confirmed first. Please provide a quote for installation only. I’m flexible with dates. Thank you!
