Tekmar with Carrier Infinity control

pipe4zen

Does any one know if a Tekmar 402 house control with a 480 user switch can connect

to Carrier's Infintity onlinr remote access control at the Aux ports. And online, can carrier be able to turn on radiant heat via user switch from an away setback temperature.



Thanks

does the remote access switch close a relay continuously?

if so, it should work. the 480 can take 3 relay demands and, in combination, receive up to 8 different "scene" commands. according to the tekmar data brochure on the 480 the relays can be dry contact or 24v powered.



default with no closed contacts on the unit is "scene 1" or normal.

Still unsure

Here is a pdf. of Carrier remote access module instructions.

There is AUX port available, just can't figure out if a Tekmar user switch would

work or not. The instructions say it will accept a dry contact, like a low temp alarm.
