in THE MAIN WALL
I have a WM Ultra 155 w/ direct hot water heater, I want to know if there is a way to use the boiler U-Control to set time that DHW makes hot water; say turning off during night and starting up in the morning.

I bought a Taco clock timer w/ aqua stat but this is to be connected to the pump, but I'm worried how that would work w/ the U-Control ? I'm thinking the boiler would be calling for the DHW to make, and yet the Timer would be cutting power to the circa pump that moves DHW?

There has to be a way the the U-Control can preform this duty? Help please...

    U-control

    There is nothing I have seen that would do what you want from the U-control.  Maybe a timer in the 24v circuit between the water heater thermostat and the boiler?  I don't think you will save much money.

    Is this for energy savings, or is the house temp not keeping up at night because of DHW priority?  There are settings to adjust if its the latter.
