C Terminal Amperage

[hands4]

Will the Nest C terminal drive a 1.25 A water valve?

Typo: I meant to ask if the W terminal can drive a 1.25 A water valve.

Never mind. The C terminals amperage is no longer an issue. I added an NC switching relay between the Nest's C terminal and the NC valve.

Hey hands4,

Awesome — glad to hear that your concern is reolsoved. It looks like we can consider this one complete, so I will lock the thread shortly unless I can help out with anything else.

Best,

How many amps do Nest thermostats draw (with the C terminal connected)?

[hands4]

I need to know the amperage because the my Taco SR506 switching relay appears to be unable to handle the amperage of four Nests. I need to know this amperage before I speak to Taco.
