Nest Thermostat showed no connection with heat link which had an Amber light at the top. Reset the heat link... No joy. Reset to factory setting. One green light up on heat sink. Thermostat working fine. Shows connection to heat link OK. Heating running on display but NO heating. Tried to bind thermostat and Link but settings for H71 error was not available. Don't know where to find "remove heat link".
Welcome any idea to resolve this problem.
