Select Sequence 1

Using a duct sensor with the CTE-5202, an automatic

changeover is provided for cooling/heating applica

tions. The duct sensor will switch the thermostat

between cooling and heating modes based on the

temperature of the duct supply air. A duct tempera-

ture higher than changeover temperature, switches

control to heating mode, and a temperature lower

than changeover temperature, switches control to

cooling mode.

Select Sequence

(from the CTE-5202

SYSTEM

menu). See

Change Configuration on page 6

and

Hot/

Cold Changeover on page 5

. The default changeover

temperature is 77° F, configurable from 55 to 85° F in

the CTE-5202

ADVANCE

menu.

NOTE: If replacing a CTE-1103 thermostat as

described in the Cooling Heating Change-

over section of the

CEP-4000 Series Ap-

plications Guide

or a CTE-5001/5011 as

described in the CTE-5001/5011 Installation

Guide, the REE-1005 or REE-1014 relay

module is not needed with the CTE-5202.

NOTE: Minimums can be set at zero air flow, but a

minimum of greater than zero is required

for a quick changeover.

NOTE: For an SSE-2001/2002 flow sensor, connect

the X and Y terminals to the CTE-5202’s AI1

and Common terminals.
