Control Arrangements - Carrier 35E Installation And Start-Up Instructions Manual

CONTROL ARRANGEMENTS

The 35E single-duct unit is offered with a wide variety of fac-
tory-mounted controls that regulate the volume of air delivery
from the unit and respond to cooling and heating load re-
quirements of the conditioned space. Stand-alone controls
will fulfill the thermal requirements of a given control space.
These devices are available in both pneumatic and electronic
arrangements. Carrier Comfort Network
i-Vu ® Open DDC (Direct Digital Controls) controllers are
communicating controls which are integrated with the build-
ing system. A number of DDC control packages by others are
available for consignment mounting, as indicated.
Control offerings are:
• 35EA (Analog Control)
• 35EC (Carrier Comfort Network
Volume [VAV] Electronic Control)
• 35ED (BACnet 1 VAV Electronic Controls)
• 35EN (No Control or direct digital controls [DDC] by
Others)
• 35EP (Pneumatic Control)
• 35EV (CCN Variable Volume and Temperature [VVT]
Electronic Control)
• 35EB (BACnet VVT Electronic Controls)
Each control approach offers a variety of operating functions;
a control package number identifies combinations of control
functions. The following listings contain the basic function
arrangements for each control offering. Because of the vari-
ety of functions available, circuit diagrams, operating se-
quences, and function descriptions are contained in separate
Application Data publications. Refer to the specific control
publication for details.
VAV Control Arrangements
The VAV units are furnished with factory-installed PICs for
integration into either the Carrier Comfort Network (CCN) or
Carrier i-Vu Open Digital Control Systems. Room tempera-
ture sensors are not included.
VVT Control Arrangement
The VVT units are furnished with factory-installed PICs for
integration into either the Carrier Comfort Network (CCN) or
Carrier i-Vu Open Digital Control Systems. Room tempera-
ture sensors are not included.

Analog Electronic Control Arrangement
Pressure-independent control packages are available without
supplemental heat, with on/off hot water or electric heat,
proportional hot water heat, or with cooling/heating
automatic changeover control.
All analog control arrangements include a standard linear in-
let flow sensor, 24-v transformer (optional), control enclosure
and wall thermostat to match the control type.
2100: Heating control
2101: Cooling control
2102: Cooling with on/off electric heat control
2103: Cooling with on/off hot water heat control
2104: Cooling/heating automatic changeover control
2105: Cooling with proportional hot water heat control
2110: Cooling with proportional (SSR) electric heat
2111: Cooling with electric heat (up to 3 Stages) and automat-
ic changeover
2113: Cooling with proportional (SSR) electric heat and auto-
matic changeover
Pneumatic Control Arrangement
All control packages are pressure independent (unless other-
wise noted) and available with or without hot water heat, dual
maximum airflow, heating and cooling maximum airflow and
dual minimum airflow. All control arrangements include a
standard linear inlet flow sensor.
