“Min Vdc Analog AO1 Output”
Default:
Range:
Increment:
0.0 Volt
0.0 to 10.0 Volts
0.1 Volt
This option does not appear if the signal ramp for AO1 is set to
OFF
(Step 24
). Select the desired minimum voltage (“zero”
value) for the AO1 ramp. The minimum value is restricted by the maximum value (Step 27). In other words, the minimum value
should be less than the maximum value.
27.
“Max Vdc Analog AO1 Output”
Default:
Range:
Increment:
10.0 Volts
0.0 to 10.0 Volts
0.1 Volt
This option does not appear if the signal ramp for AO1 is set to
OFF
(Step 24
). Select the desired maximum voltage (“span”
value) for the AO1 ramp. The maximum value is restricted by the minimum value (Step 26). In other words, the maximum value
should not be less than the minimum value.
28.
“Min Pos AO1 Output Percent”
Default:
Range:
Increment:
0%
0 to 100%
5%
This option does not appear if the signal ramp for AO1 is set to
OFF
(Step 24). Select the desired minimum position of the AO1
analog output.
29.
“Min Vdc Analog AO2 Output”
Default:
Range:
Increment:
0.0 Volt
0.0 to 10.0 Volts
0.1 Volt
This option does not appear if the signal ramp for AO2 is set to
OFF
(Step 25
). Select the desired minimum voltage (“zero”
value) for the AO2 ramp. The minimum value is restricted by the maximum value (Step 30). In other words, the minimum value
should be less than the maximum value.
30.
“Max Vdc Analog AO2 Output”
Default:
Range:
Increment:
10.0 Volts
0.0 to 10.0 Volts
0.1 Volt
This option does not appear if the signal ramp for AO2 is set to
OFF
(Step 25
). Select the desired maximum voltage (“span”
value) for the AO2 ramp. The maximum value is restricted by the minimum value (Step 29). In other words, the maximum value
should not be less than the minimum value.
31.
“Min Pos AO2 Output Percent”
Default:
Range:
Increment:
0%
0 to 100%
5%
This option does not appear if the signal ramp for AO2 is set to
OFF
(Step 25). Select the desired minimum position of the AO2
analog output.
Analog Inputs (AI1 to AI3)
32.
“Select AI1 Input Signal”
Default:
Range:
OFF
OFF, SENs, NoCl, NoHt, EtS, nSb, PrSd, PrSa
Select the input signal type for AI1 (analog input 1).
If NoCL is selected: heating mode activates when the contact is closed and cooling mode activates when the contact
is opened.
If NoHt is selected: cooling mode activates when the contact is closed and heating mode activates when the contact is
opened.
If SENs is selected: heating mode activates when the temperature read by the external sensor is above the
Changeover Setpoint and cooling mode activates when the temperature read by the external sensor is below the
Changeover Setpoint (see Step 36).
If PrSd or PrSa is selected in a pressure independent VAV system, you must perform a calibration by using the Air
Flow Program Mode (Operation Mode) on page 11.
