• rELAY is used to congure relay 1 (CodE 1) and
relay 2 (
CodE 2), see Tables 1 and 2 on the next page.
For example: To have just the drip pan, 4, and low
temp, 8, error faults enabled for relay 1 you would
enter their sum, 12, at the
CodE 1 display. To have the
tank overow, 2, the low temp, 16, and high pressure,
1024, error faults enabled for relay 2 you would enter
their sum, 1040, at the
CodE 2 display.
This display depends on your chiller
configuration, see Section 4.

• r rtd is used to enable/disable the remote temperature
sensor. See Table 3 for pin out information.
Note There is no other indication on the chiller that the
remote sensor is enabled.
• r.Start is used to enable/disable the remote start/stop.
Note Enabling analog I/O remote start/stop disables
the chiller’s local controller start/stop capability. Enabling
analog I/O remote also overrides serial communications
start/stop commands.
• r SEt is used to enable/disable the remote setpoint.
Note When remote setpoint is enabled a ashing dot will
appear on the controller's display as shown below.
• AnAin is used to congure the analog voltage input type.
Type 1: 0 - 10 VDC (Default)
Type 2: 10 mV/°C
Type 3: 4 - 20 mA
• dAC is used to enable/disable the digital to analog
converter. Once enabled, the desired output type can be
selected.
Note The Type display only appears if dAC is set to on.
Type 1: 0 - 10 VDC (Default)
Type 2: 10 mV/°C
Type 3: 4 - 20 mA

The analog input uses a 2-point calibration. Depending on how the analog input is
congured Type1, Type2 or Type 3, the HMI will display either volts, millivolts or
milliamps. The calibration procedure is:
– Start with default high and low endpoints each consisting of a voltage/current
value and a theoretical analog input value. This will permit calibration of either
point rst. Both ends must be calibrated for the entire calibration to be valid.
– Connect a 9.50v/0.400mv/20.00ma reference voltage/current source to the
analog input, pins 6 and 15.
– The HMI will display 9.50/0.400/20.00. Use the arrow keys to adjust the display
to match the applied input voltage/current.
– Allow the analog input to stabilize, approximately 10 seconds.
– Enter the measured reference voltage/current using the HMI by pressing the
key. The rmware will use this value and the theoretical analog value and
those from the low end to calculate a linear gain and offset.
– The display will automatically go to the low calibration message. Press
to
calibrate the analog input at the low end.
– Connect a 0.50v/0.050mv/4.00ma reference voltage/current source to the analog
input.
Save calibration
Do not save calibration
– The HMI will display 0.50/0.050/4.00. Use the arrow
keys to adjust the display to match the applied input
voltage/current. Allow the analog input to stabilize,
approximately 10 seconds.
– Enter the measured reference voltage/current using the
HMI by pressing the
key. The rmware will use this
value and the theoretical analog input value and those from
the high end to calculate a linear gain and offset.
– If the gain and offset are acceptable, the calibration is
accepted and the calibration is now valid at the low end.
Otherwise, the calibration is rejected and a bad calibration
error message (Er 16) is displayed.
