If you have read any of my posts you can see I'm doing a lot to my system. Now I'm still ordering parts and supplies until i have everything to do the job all at once. So the question for today is I'm going to use a Tekmar 420 with the 335 to run my boiler and zone valves, do I need a aqua stat for my SS30 or just a sensor wired into the 420 controller
Short of it is the tekmar set point will give the best performance all around becouse everything in the system will be nt4 and able to share all info. That way its one item on SS tank, less things less trouble.
At the point of wiring it all together. The Tekmar 161 setpoint is able to communicate on the house network using 4 wires. the manuals don't tell you how to wire it up. it shows how to do an aqua stat or a set point but not a set point to the dhw terminal. can someone that knows tekmar controls tell me how to do the four wires?
