What terminals should I connect my thermostat wires to in the TEKMAR 561 thermostat? No problems with 24 VAC input and sensor terminals but don't see terminals for my 2-wires that connected to old Honeywell (round) thermostat. I like the WI-FI capability of this TS so decided to upgrade. Is there another TT that I should be considering that is better? Trying to control 1-zone in my radiant heating system, will expand to a 2nd zone after connecting initial TT and testing it for WI-FI access and control of temperature.

Thx ...you guys really know this stuff.

    Do you have a Tekmar zone control too? Otherwise it won't work. Also requires you to pull 8 wire conductor (4 for sensors).

    There was an error rendering this rich post.
