The Setpoint temperature for the heating side of the Hydronic loop is set to a temperature that is higher than the Cooling Tower minimum temperature. This Setpoint sets the lower limit of the condenser water loop on the Hydronic loop. Setting this temperature to a value that is higher than the high limit side set by the cooling tower will cause the boiler to try to heat the loop to this temperature while the tower is trying to cool the loop below this temperature.
A Setpoint temperature of 65 degrees is suggested for this input.
At the Plant level of the tree, In the Heating Hot Water Tab, lower the Boiler Setpoint temperature to a value that is below the cooling tower setpoint. As an alternative, go to the Hydronic tab and select the Cooling Tower and raise the Setpoint of the Cooling Tower above the boiler setting.
