I have a taco SR503. It’s really cold in Massachusetts the past few days. If the power is lite up green and zone 1 2 3 are red, is that bad?? Thank you

[@user-yc4fb7nv5p]

Hi, did the new taco board come with the fuses or did you purchase separately? And did you cut the power to install?

[@s.d.g7761]

HI I HAVE SR504-4 Switching Relay, SAME ONE YOU USING BUT I HAVE 4 ZONE AND NAVIEAN NFC 200 COMBI BOILER. QUESTION IS WHICH WIRE I SHOULD CONNECT FROM RELAY?

[@clainwilliams7633]

Thank you for this! However what I’m not clear about is what to do with the L1 and L2 wires in the box on the boiler and also the circulator and DHW wires on the boiler.

Hi, I'm sorry I'm only seeing this now for some reason I didn't got any notification but you are probably all set now correct?

[@YARDI387]

I have a setup similar to yours. Do you have a nest hooked up to it? If so, can you show how to? I bought two nest Es and I have a 2 wire setup ..with an unused blue wire in the wall...and I'm trying to figure how to use that blue and connect to taco for c wire power

[@shalomgconstruction4136]

I do have a nest I will take a look tomorrow and upload another video how to install it.

Where you hook up your pumps from zone 1 or zone 2 in the same spot can I hook up my actuators valves ?

[@neckofthewoods24]

no you need the ZVC taco which is a controller for actuator valves.

[@kituboykituz4686]

On your Taco Controller, does your 120 V supply come from the boiler (switched) or is it straight from the main? I have the SR503 that i intend to hookup to 2 zones and a primary running with a Navien boiler.

[@shalomgconstruction4136]

Main line goes to the switch and from the switch to the the taco controller.

[@NROhvac]

Do you have an aqua stat installed? If so, is it the same 120v that feeds that the same as the 120v feeding relay control?

[@kevinzhang8337]

Hello, the green LED that usually lights up on the "POWER" part turned off and now I currently don't have any heat in the house. Do you have any suggestions on how i can fix it?

[@mrmotofy]

Make sure power switch is turned on. Make sure breaker is not tripped

[@anttwo4103]

Hey the end switch on the relay is connected to what exactly on the boiler it self ?

[@guest00101]

It depends on your boiler, but your boiler needs to know when to turn on and off. so it needs a switch from your relay board. For my boiler, it's the purple circle labeled E imgur.com/ixhkrF7

[@neckofthewoods24]

@@guest00101 what if its a hot water tank though? shouldnt it only be on when water is running through it like when you open the hot water tap on a sink?

[@Inquisitor6321]

@@guest00101 Thanks! I wonder that myself. You were a big help to me.

[@ypcharly]

Where does the thermostat coming from the boiler connects to?

[@shalomgconstruction4136]

Thermostat only goes to the SR-504-4 not to the boiler.

[@ypcharly]

Thank you.

[@neckofthewoods24]

@@shalomgconstruction4136 my thermostat says X and C and the controller is R and W. wish everyone made it the same letters.
