Hi,I replaced my Honeywell T87N1018 with a Nest Thermostat E. The Nest E works fine in the summer when the cooling system is on, but as soon as they flip over to heating, Nest gives me an error about not having power. Some perspective...my GTA condo ...

So is this what’s preventing Nest E from working when they switch over to heat?

Thank you for responding. Yes…they pump cold water in summer and hot in winter. In summer we can control the a/c, but can’t turn on the heater. No separate units outside.
