LavaTap Pro Controls 7 Day 2 Channel Heating Programmer Direct Replacement for Honeywell ST9400C Heating Hot Water Control Compatible with Honeywell ST699 ST799 ST7100, White

Easy to replace

After my Honeywell st9400c heating controller started to flash like a 90s rave I did a little research. After a few minutes found this made by Resideo it's almost identical and fits directly onto the same wired back plate so no wiring involved. It's a 10 minute job to swap over just check the programme on your existing controller in the installer programming mode and change it if necessary. It's been working for a while now and my heating is working properly so the jobs a good un.

Product did exactly what it said on the timeFitted perfectly and worked

Can some one contact me re this as it has just failed the display has gone blank. Item was easy to change and worked perfectly up to now. Rate at 5 star until the display failed.
