CONTROLS INSTALLATION

Constant Volume (CV) Units — The 48ZG,ZT,Z6 units may be used in applications with additional control features, options, or accessories. Refer to the appropriate accessory installation instructions for more information on installing that accessory. Control options and accessories available for CV units are:

•thermostats

•enthalpy sensor

•enthalpy switch

•relative humidity sensor

•CEM (controls expansion module)

•Navigator™ hand-held display

CONTROL WIRING — The unit can be controlled with a Carrier-approved accessory electro-mechanical or electronic thermostat that has two stages of cooling, two stages of heating control, and an output for fan control. The thermostat may also include time of day scheduling or use scheduling routines built into the ComfortLink™ controls.

Install the thermostat according to the installation instruc- tions shipped with the accessory thermostat. Locate thermostat assembly on a solid interior wall to sense average temperature.

Route thermostat cable or equivalent leads of colored wire from subbase terminals through conduit into the low voltage connections in the main control box. For thermostat TB203 connections, see Fig. 67.

NOTE: For wire runs up to 50 ft, use no. 18 AWG (American Wire Gage) insulated wire (35 C minimum). For over 75 ft, use no. 14 AWG insulated wire (35 C minimum). All wire larger

than no. 18 AWG cannot be directly connected at the thermostat and will require a junction box and splice at the thermostat.

Variable Air Volume (VAV) Units — The 48ZN, ZW, Z8 units may be used in applications with additional con- trol features, options, or accessories. Refer to the appropriate accessory installation instructions for more information on in- stalling that accessory. Refer to the Controls and Troubleshoot- ing manual for more information concerning installation and configuration of options and accessories. Control options and accessories available for VAV units are:

•enthalpy sensor

•enthalpy switch

•relative humidity sensor

•CEM (controls expansion module)

•Navigator hand-held display

•VFD remote display

SENSORS — Sensors should be wired using single twisted pairs of 20 AWG (American Wire Gage) conductor cable rated for the application, except for the T-56 accessory sensor which requires 3-conductor cable.

NOTE: Humidity and CO2 sensors must be powered from isolated 24-v power supplies.

HUMIDITY CONTROL AND HOT WATER AND STEAM VALVES — These devices require 20 AWG twisted pair conductor cables rated for the application for the 4 to 20 mA signal.

SPACE TEMPERATURE SENSOR (T-55) — The space tem- perature sensor (P/N 33ZCT55SPT) is shipped standard with every unit, and is located in the main control box. Space tem- perature sensor wires are to be connected to terminals in the unit main control box.

CAUTION

Jumper MUST be in place between pins 1 and 3, 3 and 4 or inaccurate readings could result.

To connect the space temperature sensor, see Fig. 68.
