hi... I am wanting to change my SONDER TR01 COD 1001 manual thermostat to a HONEYWELL DT90E + ECO digital but am not sure about the wiring. my old one has three wires red / black / earth . the live is connected to no.1 terminal and the black is connected to no.3 and obviously earth to earth terminal. the honywell has only 2 connectors. what do I do with the earth wire ( put it in a terminal block ? ) and which wire goes where on the digital connections
any help please
