Then I purchased the nest power connector, hoping to eliminate the warning. After install and update I noticed that the warning notice gone, however, it won't turn on the valve. Then I used my multimeter to check the continuity in the connector, found only R wires have continuity, the W*Y wire does not. Is that normal for this connector?</SPAN></P> Sun, 28 Nov 2021 04:29:07 GMT leonshiyan 2021-11-28T04:29:07Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Might-receive-a-defective-nest-power-connector/m-p/51693#M11381 <P><BR /><SPAN>I bought a google nest thermostat to replace the old Honeywell mechanical thermostat, which is a 2 wire(W/R) zone valve control.</SPAN><BR /><SPAN>Works great while running with battery only with n260 warning.

I usedthe transformer 24v pine to get the power for the c wire&nbsp;</P> Tue, 18 Jan 2022 16:44:51 GMT https://www.googlenestcommunity.com/t5/Nest-Thermostats/Might-receive-a-defective-nest-power-connector/m-p/86473#M19369 Jazzmen 2022-01-18T16:44:51Z
