7.D.4 Heat Demands
TT1 - if a thermostat/aquastat or end switch (isolated
contact only) is used as a heat demand, connect to
terminals 37 and 38 (See Figure 19 on page 37).
TT1 functionality is congured on the touch screen on
the CH1/DHW1 screens.
TT2 – if an additional thermostat/aquastat or end switch
(isolated contact only) is required as a heat demand,
connect to terminals 39 and 40. TT2 functionality is
congured on the touch screen on CH2/DHW2 screens.
DHW – if an aquastat, end switch (isolated contact
only), or ow switch is used as a DHW heat demand,
connect to terminals 41 and 42. If preferred, a DHW
tank sensor can be used in lieu of an aquastat to
generate a heat demand.
NOTE: TT1, TT2, and DHW heat demand contacts must
be dry contacts. The controllers heat demand voltage is
24VDC.
Refer to CH1 in 8.G on page 98– Heat Demands.
7.D.5 Analog In and Analog Out
Inputs
BMS – if an analog input (0-10VDC or 4-20mA) from a
BMS is used as a remote set point or remote ring rate
command, wire to terminals 43 and 44 (See Figure 19
on page 37). Polarity is shown on the terminal label.
Selecting voltage or current input is accomplished
through jumper placement on the control board. Analog
BMS functionality is congured using the touch screen.
Blower – this input is factory wired. When using a
VFD for blower speed control, this input provides speed
feedback from the VFD to the controls.
Outputs
Pump – when using Vari-Prime pump control, wire the
pump speed wires to terminals 47 and 48. Polarity
is shown on the terminal label. Selecting voltage
or current output is accomplished through jumper
placement on the control board. Vari-Prime functionality
is congured using the touch screen.
Blower – this output is factory wired. When using a
VFD for blower speed control, this output provides the
speed signal to the VFD.
7.D.6 Dry Contacts. Run & Alarm
Run - when used, is connected to terminals 51
(common), 52 (normally closed), and 53 (normally open)
(See Figure 19 on page 37). The controller closes
the normally open set of contacts whenever the unit is
running. Contact ratings are 250VAC, 0.6A maximum.
Alarm - when used, is connected to terminals 54
(common), 55 (normally closed), and 56 (normally
open). The controller closes the normally open set
of contacts whenever the unit is locked out. Contact
ratings are 250VAC, 0.6A maximum.
