Elec rough in.
The 654 control should modulate the boiler with a 0 to 10 volt signal.
We plan to leave stubs for adding a dhw tank when needed.0 -
Got it all up and running today.
I have it set to idle with a 40f slab temp for a few days, figure it will help the concrete finish curing.
Looking forward to the first good snow0 -
Question about pump size...
If my primary and secondary loops show the same supply and return temps does that mean my pumps are well matched?
Delta t is about 20 f right now when running full blast with a 35 f slab temp.0 -
20 delta is well suited for snowmelt. What are your temps to the slab? Be careful heating slab that is not fully cured. You down want to create much thermal gradient. Low temp with insulating blankets would be ideal."If you can't explain it simply, you don't understand it well enough"

Just tinkering around with the settings.
If I max out the boiler by using the override setting on the tekmar I was getting about 18 degrees delta.
Setting it to idle last night at 40 degrees slab it modulated the boiler way down.
Probably only a few degrees on the delta temp.0
