13. “Ch over temper sensor”
Default:
Range:
SENs (external changeover sensor)
SENs, NoCl, NoHt
• 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 14)
• If NoHt is selected: heating mode activates if the contact is opened and the cooling mode activates if the contact is
closed. (see Step 14)
• If NoC is selected: heating mode activates if the contact is closed and cooling mode activates if the contact is open.
If you selected NoCl or NoHt option, go to Step 21.
14. “Ch over setpnt temper”
Default:
Range:
Increment:
24.0ºC [75ºF]
10.0 to 40.0ºC [50 to 104ºF]
0.5ºC [1ºF]
This option appears if you have set one of the analog inputs to SENs (external changeover sensor) at Step 13. Set the desired
changeover temperature setpoint. Note that the 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.
Go to Step 21.
15. “select 4 pipe heating signal”
Default:
Range:
AnLG (Analog)
AnLG (Analog), OnOf (On /Off), PULs (Pulse)
This option appears if you have selected 4P at Step 8. Select the heating signal for your 4 pipe system.
• If you select AnLG ((Analog), AO2 will be set to heating.
• If you select OnOf (On/Off), or PULs (Pulse), TO2 will be set to heating.
If you selected OnOf or PULs signal, go to Step 18.
16. “min vdc analog output heating”
Default:
Range:
Increment:
0.0 Volt
0.0 to 10.0 Volt
0.1 Volt
Select the desired minimum voltage (zero value) for heating ramp. The minimum value (Step 16) is restricted by the maximum
value (Step 17). In other words, the minimum value must be less than the maximum value.
17. “max vdc analog output heating”
Default:
Range:
Increment:
10.0 Volt
0.0 to 10.0 Volt
0.1 Volt
Select the desired maximum voltage (span value) for heating ramp. The maximum value (Step 17) is restricted by the minimum
value (Step 16). In other words, the maximum value must be greater than the minimum value.
18. “select 4 pipe cooling signal”
Default:
Range:
AnLG (Analog)
AnLG (Analog), OnOf (On/Off)
This option appears if you have selected 4P at Step 8. Select the desired cooling signal output for your 4 pipe system.
• If you select the AnLG (analog) signal, AO1 will be set to cooling.
• If you select the OnOf (on/off) signal, TO1 will be set to cooling.
If you selected the OnOf signal, go to Step 21.
19. “min vdc analog output cooling”
Default:
Range:
Increment:
0.0 Volt
0.0 to 10.0 Volt
0.1 Volt
Select the desired minimum voltage (zero value) for cooling ramp. The minimum value (Step 19) is restricted by the maximum
value (Step 20). In other words, the minimum value must be less than the maximum value.
