TEC3000 Series On/Off or Floating Fan
Coil Thermostats Installation Guide
Applications
The networked TEC3000 Series Thermostat Controllers are stand-alone and field-selectable
BACnet
®
MS/TP or N2 networked devices. Wireless networked models of the TEC3000 Series
Thermostat Controller are also available. On/Off or Floating Fan Coil and Individual Zone
Thermostat Controllers provide control of the following:
• Local hydronic reheat valves
• Pressure-dependent variable air volume (VAV) equipment with or without local reheat
• Two- or four-pipe fan coils
• Cabinet unit heaters
• Other individual zone equipment using an on/off or floating control input
The networked models feature a field-selectable Building Automation System (BAS) BACnet MS/
TP or N2 communication capability that enables remote monitoring and programming for efficient
space temperature control. The wireless models are compatible with the WNC1800/ZFR182x Pro
Series Wireless Field Bus System that enables communication with a building automation system
(BAS). All models include a USB port configuration that reduces installation time by allowing
simple backup and restore features from a USB drive, which enables rapid cloning of configuration
between like units.
Some models feature built-in occupancy sensing capability. These thermostat controllers maximize
up to 30% energy savings in high-energy usage commercial buildings, such as schools and hotels,
during occupied times by using additional standby setpoints.
All models feature an intuitive onboard touchscreen UI with backlit display that makes setup and
operation quick and easy. Multiple fan configurations are supported for fan coil equipment types,
as follows:
• Single-speed
• Multi-speed (two or three discrete speeds)
• Variable-speed/EC motors (0 to 10 VDC control)
Some models support dehumidification on two-pipe fan coil units with reheat, and four-pipe fan
coil units with or without reheat. When no heating is required, the thermostat controller monitors
space humidity and activates dehumidification control as necessary. Heat and/or reheat is used as
required to maintain the space temperature. For optimal dehumidification performance, use a fan
coil unit that has a multi-speed or variable-speed fan (VSF).
Important:
The TEC3000 Series 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.
