Line voltage T156 thermostat — Includes thermostat
for 2-pipe or 4-pipe system and manual 3-speed fan con-
trol. The special combination allows for the fan coil unit to
have control for the valve cycle only. This thermostat is
only available for unit-mounted line voltage applications.
Integrated Direct Digital Controls (DDC)
Fan Coil Open controller — The factory-mounted con-
troller continuously monitors and regulates the fan coil
operation with reliability and precision. This advanced con-
troller features a sophisticated, factory engineered control
program that provides optimum performance and energy
efficiency. The fan coil open controller also features plug-
and-play connectively to Carrier’s i-Vu
®
Open control sys-
tem. For added flexibility, the fan coil controller is capable
of stand alone operation, or can be integrated with any
Building Automation System (BAS) utilizing BACnet proto-
col. Application features include built-in advance control
routines for zone level humidity control, zone level demand
ventilation (ASHRAE 62) and automatic fan speed control
based on demand. System benefits include demand limiting
for maximum energy saving, and compatability with i-Vu
control system tenant billing for tracking tenants after
hours energy usage. Hardware features include onboard
hardware clock, remote occupancy input, and support for
space temperature thermistor sensor for stand alone
operation.
