Tekmar 150 Settings

in THE MAIN WALL
I have a 3 zone in-slab area and a 2 zone staple-up with pans area both controlled with separate tekmar 150 set point units. Can anyone suggest settings for the differential and cycle time variables?

I have a 200K BTU NTI boiler with a tekmar 356 control and outdoor resets.

I have been running with differential setting of 4F and a cycle time mode of 4 minutes in Pulse mode. I looking for help fine tuning these settings.

Dan.

    why mix?

    if i'm not mistaken, the nti has a (primitive) onboard ODR control, using a 356 mixing control kind of defeats the purpose of a condensing boiler, you want the lowest return temps you can get to maximize the boilers efficiency.

    i would set the curve of the boiler to meet the demand of your highest temp zone (staple up) and use the 356 to mix down for the in-slab.
