Table 33 — C.TYP=7 (Pct Cap) Required Configuration
*Although return air and supply air thermistors are not required, they
can be configured. If they are not installed, the values for
RAT.T
and
SAT.T
must be set to
2
.

NOTES:
1. Field wiring must be in accordance with local codes.
2. LVT-1 and 2 are for the alarm relay. The maximum load allowed for the alarm relay
is 5 VA sealed, 10 VA at 24 VAC. Field power supply is not required.
3. LVT-24, 25, and 2 are for control of field-supplied liquid line solenoid valve (LLSV)
15 VA sealed, 30 VA inrush at 24 VAC. Field power supply is not required.
4. For 38APD070-130 units, an additional LLSV, 15 VA sealed, 30 VA inrush at 24
VAC can be connected to CXB. A field-supplied control transformer is required, not
to exceed 75 VA.
5. All discrete inputs are 24 VAC.
6. Installation of fan status switch (FS1) is recommended. If not used, a jumper must
be installed.
7. Energy management module (EMM) is required.
8. The contacts for Remote On-Off, Fan Status Switch and Demand Limit must be
rated for dry circuit applications capable of handling a 24 VAC load up to 50 mA.
