CONFIGURATION
NOTE: By default, the control sensor
is the unit outlet sensor, or when
installed, the system supply sensor.
8.D.1.a.1 PID Parameters
Note that in most cases, PID parameters will not need to be changed. The PID Parameters Screen allows adjustment
to the following parameters:
• On Hysteresis – The temperature below the set point (Set Point – On Hysteresis) at which the control begins
calculating the PID output to turn on stages.
•OHysteresis – The temperature above the set point (Set Point + O Hysteresis) at which the controller will stop
calculating the PID output and set the PID output to 0 to turn o all stages.
• Proportional Gain – This value is the
corrective action that is proportional to the
error (set point – control temperature).
• Integral Time – This value is applied to the
sum of the error over a period of time.
• Derivative Time – This value is applied to
the rate of change of the error.
PID
8.D.1.b CH2 (Central Heat, Two)
Additional heat demands CH2, are available and are set up in the same manner as CH1.
8.D.2 DHW
(Domestic Hot Water)
To navigate to the DHW Screen, touch the DHW faucet icon on the Congure Screen.
DHW has all the same parameters as CH1 and CH2 with one exception. DHW has the following additional
parameters for adjustment:
•DHWOset– Upon a DHW heat demand, the unit will control the outlet temperature to the DHW Set Point plus the
DHW Oset (set point + DHW Oset).
For example, with a DHW Set Point of 140°F
and a DHW Oset of 40°F, the unit will control
the boiler/heater outlet temperature to 180°F
(140°F + 40°F) to satisfy the heat demand.
NOTE: A DHW heat
demand can be initiated by
an aquastat or sensor.
