Optional Remote Temperature Sensors Installation

Wire specification for remote sensors: 2 conductors, 18 gauge wire. Make sure that the sensor wires are installed in a separate cable from the wiring to the HVAC system. Best results for distances of 100 feet or less. Accuracy may be affected for distances up to a maximum of 200 feet. Shielded cable is recommended for distances over 100 feet and less than 200 feet.

CAUTION: Keep this wiring at least one foot away from large inductive loads such as electronic air cleaners, motors, line starters, lightning ballasts, and large distribution panels. Failure to follow these wiring practices may introduce electrical interference (noise) which can cause erratic system operation. Shielded cable is required if the above wiring guidelines cannot be met. Be sure to ground only one end of the shield to the Comfort Control common terminal. Tape back the other end of the shield.

Remote Sensors Part Numbers

Remote Indoor Sensor: Use ZZSENSAL0400AA for indoor applications.

Remote Outdoor Sensor: Use BAYSEN01ATEMPA for outdoor applications.

> IMPORTANT: Make sure that the sensor wires are installed in a separate cable from the Comfort Control cable.

> IMPORTANT: Follow directions below for averaging. These instructions replace the averaging information found in the Installer’s

Guide for the ZZSENSAL0400AA.

Remote Temperature Sensor Connections and Operation:

A) Indoor sensor connected to RS.

The Remote Sensor (RS) function can be configured in the

Service/Installer Settings/Sensor Settings menu. Options are:

• None

• Replaces onboard temp sensor of the Comfort Control

• Averages with onboard temp sensor

Replace - RS Sensor replaces the internal temperature sensor of the Comfort Control. This allows the Comfort Control to be installed in a location different than the area where the temperature will be measured. Use ZZSENSAL0400AA.

RS

RS

Remote

Sensor

Average - RS Sensor averages its temperatures with the internal sensor. Use ZZSENSAL0400AA.

ODT

Outdoor

Comfort Setting

Description

When dehumidification is enabled, the control will reduce system airflow by 30% (variable speed indoor units only) anytime the indoor humidity is higher than the cooling target humidity setpoint and the indoor temperature is within 2°F of cooling setpoint. All fan off delays will also be cancelled.

Select the maximum amount of overcooling allowed when the indoor humidity exceeds the cooling target humidity setpoint. To accomplish the overcooling the control will artificially create additional load by increasing the sensed indoor temperature by 1/10th of a degree for every 1% of humidity error, up to the overcooling limit selected. The displayed indoor temperature will remain the same, but the adjusted indoor temperature will control cooling operation.

When enabled the indoor blower speed will be limited to 80% on a call for heat pump heating. This only applied to heat pump heating with no call for aux heat. An indoor unit with variable speed blower is required.

Recovery Enable Yes, [No] When enabled, will start the cooling or heating system so that the desired comfort temperature is reached by the next scheduled set point time. The advance start time calculation is a learned process that is recalculated and adjusted each day until the room temperature is at the target temperature at the schedule time. When the thermostat is in Recovery mode the display will show “Recov”. While in Recovery the Aux-Heat stage will not engage. The maximum Recovery time is one hour.

Base Limited Warranty

Subject to the terms and conditions of this limited warranty, Trane U.S., Inc. (“Company’) extends a limited warranty against manufacturing defects for the product(s) identified in Tables 1, 1A, 1B attached hereto (“Products’) that are installed in a residential/multi-family application (personal, family or household purposes) under normal use and maintenance in the United States and Canada.

This limited warranty applies to Products manufactured on or after August 1, 2011.

In order to maximize the available benefits under this limited warranty, the Purchaser (as defined below) should read it in its entirety. All repairs of Product parts covered under this limited warranty must be made with authorized service parts and by a licensed HVAC service provider. Additionally, commercial applications are treated differently under this limited warranty as stated in Tables 1, 1A, 1B attached hereto. For purposes of this limited warranty, “commercial applications” shall mean any application other than for personal, family, or household use.

TERM: The limited warranty period for Products is as stated in Tables 1, 1A, 1B attached hereto. If the Purchaser properly registers the Products, the limited warranty period shall be extended as stated in Tables 1, 1A, 1B attached hereto. Regardless of registration, the Commencement Date for a limited warranty period shall be the date that the original installation is complete and all Product start-up procedures have been properly completed and verified by an installer’s invoice. If the installation and startup date cannot be verified by the installer’s invoice, the Commencement Date shall be sixty (60) days after the factory manufacture date which is verified by the Product serial number.
