MAT SET
53ºF
38 to 70ºF;
in cre ment by 1
Setpoint de ter mines where the economizer will mod u late the OA damper to main tain the mixed
air tem per a ture.
LOW T LOCK
32ºF
-45 to 80ºF;
in cre ment by 1
Setpoint de ter mines out door tem per a ture when the me chan i cal cool ing can not be turned on.
Com monly re ferred to as the Com pres sor lockout.
DRYBLB SET
63ºF
48 to 80ºF;
in cre ment by 1
Setpoint de ter mines where the economizer will as sume out door air tem per a ture is good for free
cool ing; e.g.; at 63ºF unit will economizer at 62ºF and be low and not econ o mize at 64ºF and
above. There is a 2ºF deadband.
ENTH CURVE
ES3
ES1, ES2, ES3,
ES4, or ES5
Does not dis play if a field in stalled Dual Enthalpy kit is con nected. Enthalpy bound ary "curves"
for econ o miz ing us ing sin gle enthalpy com par i son be tween out door air enthalpy and setpoint.
DCV SET
1100 ppm
500 to 2000 ppm
in cre ment by 100
Dis plays ONLY if field in stalled CO
2
sen sor is con nected. Setpoint for De mand Con trol Ven ti la -
tion of space. Above the setpoint, the OA damp ers will mod u late open to bring in ad di tional OA
to main tain a space ppm level be low the setpoint.
MIN POS
2.8 V
2 to 10 Vdc
Dis plays ONLY if a CO
2
sen sor is NOT con nected.
With 2-speed fan units MIN POS L (low speed fan) and MIN POS H (high speed fan) set -
tings are re quired. De fault for MIN POS L is 3.2V and MIN POS H is 2.8V
VENTMAX
2.8 V
2 to 10 Vdc
Dis plays only if a field in stalled CO
2
sen sor is con nected. Used for Vbz (ven ti la tion max cfm)
setpoint. VENTMAX is the same set ting as MIN POS would be if you did not have the CO
2
sen -
sor.
100 to 9990 cfm
in cre ment by 10
If OA, MA, RA and CO
2
sen sors are con nected and DCV CAL EN ABLE is set to AUTO mode,
the OA damp ers are con trolled by CFM and dis plays from 100 to 9990 cfm.
2 to 10 Vdc
With 2-speed fan units VENTMAX L (low speed fan) and VENTMAX H (high speed fan)
set tings are re quired. De fault for VENTMAX L is 3.2V and VENTMAX H is 2.8V.
VENTMIN
2.25 V
2 to 10 Vdc
Dis plays only if field in stalled CO
2
sen sor is con nected. Used for Va (ven ti la tion min cfm)
setpoint. This is the ven ti la tion re quire ment for less than max i mum oc cu pancy of the space.
100 to 9990 cfm
in cre ment by 10
If OA, MA, RA and CO
2
sen sors are con nected and DCV CAL EN ABLE is set to AUTO mode,
the OA damp ers are con trolled by CFM and dis plays from 100 to 9990 cfm.
2 to 10 Vdc
With 2-speed fan units VENTMIN L (low speed fan) and VENTMIN H (high speed fan) set -
tings are re quired. De fault for VENTMIN L is 2.5V and VENTMIN H is 2.25V.
ERV OAT SP
32ºF
0 to 50ºF;
in cre ment by 1
Only when AUX1 O = ERV
EXH1 SET
50%
0 to 100%;
increment by 1
Setpoint for OA damper po si tion when ex haust fan 1 is pow ered by the economizer. With
2-speed fan units Exh1 L (low speed fan) and Exh1 H (high speed fan) set tings are re quired.
De fault for Exh1 L is 65% and Exh1 H is 50%.
EXH2 SET
75%
0 to 100%;
increment by 1
Setpoint for OA damper po si tion when ex haust fan 2 is pow ered by the economizer. Only used
when AUX1 O is set to EHX2.
With 2-speed fan units Exh2 L (low speed fan) and Exh2 H (high speed fan) set tings are re -
quired. De fault for Exh2 L is 80% and Exh2 H is 75%.
