0-10VDC - As shown in Fig. 18, connect input to
Microboard J22-3 (signal) and J22-5 (Gnd). A 0VDC
signal produces a 0°F offset. A 10VDC signal pro-
duces the maximum offset (10 or 20°F above the Lo-
cal Setpoint value). The setpoint is changed linearly
between these extremes as the input varies linearly
over the range of 0VDC to 10VDC. This input will
only be accepted when “Analog” Remote Mode is
selected., the “Remote Analog Input Range”
setpoint is set for “0-10VDC” and Microboard Pro-
gram Jumper JP24 has been removed. Calculate the
setpoint for various inputs as follows:
OFFSET(°F) = (VDC)(REMOTE RESET TEMP. RANGE)
10
SETPOINT (°F) = LOCAL SE OFFSET
For example, if the input is 5VDC and the Remote Re-
set Temp Range setpoint is programmed for 10°F and
the Local Leaving Chilled Liquid Temperature setpoint
is programmed for 40°F, the setpoint would be set to
45°F as follows:
OFFSET (°F) = 5 X 10
10
= 50

= 5°F
SETPOINT (°F)
= 40 + 5
= 45°F
2-10VDC - As shown in Fig. 18, connect input to
Microboard J22-3 (signal) and J2-5 (Gnd). A 2VDC
signal produces a 0°F offset. A 10VDC signal produces
the maximum allowed offset (10°F or 20°F above the
Local Setpoint Value). The setpoint is changed linearly
between these extremes as the input varies over the
range of 2VDC to 10VDC. This input will only be ac-
cepted when “Analog” Remote Mode is selected,
the “Remote Analog Input Range” setpoint is set
for “2-10VDC” and the Microboard Program Jumper
JP24 has been removed. Calculate the setpoint for vari-
ous inputs as follows:
OFFSET (°F) = (VDC – 2)(REMOTE RESET TEMP. RANGE)
8
SETPOINT (°F) = LOCAL SE OFFSET
For example, if the input is 5VDC and the Remote Re-
set Temp. Range setpoint is programmed for 40°F, the
setpoint would be set to 43.8°F.

changed over the range of 10° or 20ºF (as per the lo-
cally programmed Remote Reset Temperature
Range setpoint) above the Local Leaving Chilled Liq-
uid Temperature Setpoint. For example, if the Local
Setpoint is 40°F and the Remote Reset Tempera-
ture Range setpoint is programmed for 10°F, the Leav-
ing Chilled Liquid Temperature setpoint can be remotely
reset over the range of 40°F to 50°F. The Control Cen-
ter must be configured appropriately to accept the de-
sired signal type as follows:
• The appropriate Remote Mode must be selected:
Analog Remote Mode must be selected when
using a voltage or current signal input. Digital Re-
mote Mode must be selected when using a PWM
input.
• If Analog Remote Mode is selected, the Remote
Analog Input Range setpoint must be set to
“0-10VDC” or “2-10VDC” as detailed below, re-
gardless of whether the signal is a voltage or cur-
rent signal type.
• Microboard Program Jumper JP24 must be posi-
tioned appropriately per the input signal type as de-
tailed below. It is recommended a qualified Service
Technician position this jumper.
Important! The signal type used for
Remote Leaving Chilled Liquid Tem-
perature setpoint reset and the signal
type used for Remote Current Limit
setpoint reset must be the same. For
example, if a 0-10VDC signal is be-
ing used for Remote Current Limit
Setpoint, then a 0-10VDC signal must
be used for Leaving Chilled Liquid
Temperature reset.
