YCCS TEC2603-4 BACnet® MS/TP Networked Multi-Stage
Applications
The TEC2603-4 Thermostat Controller is a BACnet®
Master-Slave/Token-Passing (MS/TP) networked
device that provides control of multi-stage heating/
cooling equipment in York Commercial Comfort System
(YCCS) applications.
The TEC2603-4 Thermostat Controller features an
intuitive User Interface (UI) with backlit display that
makes setup quick and easy. The thermostat controller
also employs a unique, Proportional-Integral (PI)
time-proportioning algorithm that virtually eliminates
temperature offset associated with traditional,
differential-based thermostat controllers.
IMPORTANT: The TEC2603-4 Thermostat
Controller is intended to provide an input to
equipment under normal operating conditions.
Where failure or malfunction of the thermostat
controller could lead to personal injury or property
damage to the controlled equipment or other
property, additional precautions must be designed
into the control system. Incorporate and maintain
other devices, such as supervisory or alarm systems
or safety or limit controls, intended to warn of or
protect against failure or malfunction of the
thermostat controller.

Mounting
Location Considerations
Locate the TEC2603-4 Thermostat Controller:
• on a partitioning wall, approximately 5 ft (1.5 m)
above the floor in a location of average
temperature
• away from direct sunlight, radiant heat, outside
walls, outside doors, air discharge grills, or
stairwells, and from behind doors
• away from steam or water pipes, warm air stacks,
unconditioned areas (not heated or cooled), or
sources of electrical interference
Note: Allow for vertical air circulation to the
TEC2603-4 Thermostat Controller.
Installation
To install the thermostat controller:
1. Use a Phillips-head screwdriver to remove the
security screw if it is installed on the bottom of the
thermostat controller cover.
Note: Normally, the security screw is packaged
separately in a plastic bag with the thermostat
controller. Skip this step if the screw is not installed
on the bottom of the cover.
2. Pull the bottom edge of the thermostat controller
cover and open the thermostat controller as
illustrated in Figure 1.
