the instalation ok but didnt take time to show how to work control resulting in heating on during night and then came home in afternoon and heat on again, the quick start leaflet needs looking at as the instructions are not just for the customer. it talks about wiring diagram, open therm. thermostat terminals description, landlord settings etc. I feel it would be better if there was a simple quick start leaflet.I had to google instructions which didnt help, there wasnt a subtitle, manual over ride, so I could operate the control without setting days and times. I rang glow green I got an email from REED saying he would be in touch, then today I got another message saying he couldnt get a response I checked my phone and I havent missed any calls .I dont think that is good customer service all he did then was send details of a website to get help, to me that is poor customer service
