maximum. DHW pump functionality is congured using
the touch screen.
System Pump - If connecting a system pump, use
terminals 29 and 30. As this is a dry contact, the system
pump supply voltage or system pump relay coil voltage
would be applied at terminal 29, and when the system
pump is activated, power will be available at terminal
30. Contact ratings are 250VAC, 1.5A maximum.
System pump functionality is congured using the touch
screen.
Isolation Valve – See Section 7.E.5 on page 42
Alarm Bell – If connecting an alarm bell, use terminals
33 and 34. As this is a dry contact, the alarm bell
supply voltage is applied at terminal 33, with the alarm
bell connected to terminal 34.
7.E.3 Temperature Sensors
System Supply - If used, connect to terminals 35 and
36 (See Figure 20 on page 40). When connected,
the controller automatically detects the presence of
this sensor and the temperature is shown on the home
screen above the red system supply arrow. When
installed, the unit controls the ring rate to maintain
the system supply temperature to the heat demand set
point.
System Return - If used, connect to terminals 37 and
38. When connected, the controller automatically
detects the presence of this sensor and the temperature
is shown on the home screen above the blue system
output arrow.
Domestic Hot Water (DHW) - If used, connect to
terminals 39 and 40. When connected, the unit will use
this sensor to perform the DHW thermostat function and
the temperature is shown on the home screen below
the faucet icon. The controller automatically detects
the presence of this sensor and initiates a call for heat
when the DHW temperature drops below the DHW set
point by the value of the DHW On Hysteresis (DHW Set
Point – DHW On Hysteresis = DHW heat demand).
Outdoor - If used, is connected to terminals 41 and
42. When connected, the controller automatically
detects the presence of this sensor and the temperature
is shown on the home screen as the Outdoor air
Temperature (OAT). If installed, options such as outdoor
reset and warm weather shutdown can be enabled
through the display. Always install the Outdoor Sensor
at an outdoor location that is not aected by false
temperature readings such as elevated readings from
sunlight or hot equipment.
7.E.4 Safety Chain
Field Interlock - If a eld installed interlock (dry contact
only) is used, connect to terminals 43 and 44. When
open, the interlock will open the safety chain, removing
the heat demand. When closed, this interlock in the
safety chain is satised.
