T7080 Electronic Dual Setpoint Thermostat

Used in W7080 control system to provide modulating space
temperature control.

• Separate heat and cool adjustable set point levers provide adjustable
deadband from 3 F to 30 F (2 C to 17 C)

• Single 2 to 22 Vdc voltage ramp provides heating/cooling signal to
W7080 Load Analyzer

• Outputs constant 12 Vdc when sensed temperature is
within deadband range

• Ramp output decreases on call for heat: increases on call for cooling

• C7100B or C7046B Air Temperature Sensors are used to provide
heating/cooling anticipation (one required for each zone thermostat)
and can also be optionally used as remote return air temperature
sensors with the T7080B transmitter

• Operates on 24 Vdc supplied by W7080A Load Analyzer

• Mounts on standard 2 x 4 in. outlet box or on nonconductive flat surface

W7080 Load Analyzer

Controls heating, cooling and space demand oriented economizer
operation in the Honeywell Electronic Dual Set point Multizone
control system.

• Controls 3 stages of on/off heating, modulated heating, modulated
economizer, 3 stages of on/off cooling and modulated cooling

• Responds to highest heating and cooling demand signal from
up to 12 T7080 Zone Thermostat/Transmitters

• Analyzer is short-circuit protected source of 24 Vdc power for zone
thermostat/transmitter, sensor and W7081A Limit Controller Package

• Switches all stages off when power is interrupted; switches stages
on when power is restored

• Compressor turn-on time delays must be incorporated for each compressor

• No adjustment or calibrations required

• Night setback and cooling shutdown for individual or all zones
by addition of time-clock

• Mounts with 4 No. 8 Screws (not provided) through holes in base

Application Size:
Dimensions, Approximate: 6 1/4 in. high x 4 1/8 in. wide x 2 5/16 in. deep

(159 mm high x 105 mm wide x 59 mm deep)
