External mounting tabs do not require cover removal to install

Colored cover gasket indicates proper cover seal

Compact, lightweight size means easy handling, lower shipping costs

Large terminal connection screws

Standard interchangeable "plug-in" UL268 photoelectric or ionization heads

Advanced detector head design yields internal dust filtering

No additional screens or filters to clean

Compatible with building automation and fire alarm systems

Ionization and Photoelectric versions available

Complete wiring details permanently attached to unit

Made in USA

Simplified installations with multi-speed fans, inaccessible air handlers, fan motors with voltage or phase different from controlled equipment

Eliminated wiring to system fan

Polyester film sail mounted on a micro switch snap switch

Removable spring counterbalances sail to allow mounting in either vertical (up or down) or horizontal air flow

Top and bottom conduit knockouts for wiring convenience

Low air velocity switch operation makes at 250 fpm and breaks at 75 fpm

Models with setpoint adjustment

Models with occupied/unoccupied override (bypass) with LED

Models with 3-position (auto/0/1) or 5-position (auto/0/1/2/3 speed) fan switch

LONWORKS network jack on all models except the TR21 and TR21-A models

Solid State Thermistor Element Provides Accurate Sensing of Temperature Changes

Unit mounted C7400S enthalpy sensor includes solid state temperature and humidity sensors

Outputs a digital communicating signal on a two-wire Sylkbus communications link, reporting the temperature and humidity separately to the controller

The controller determines the enthalpy (total heat), enabling economizer modes of operation when outside air enthalpy is suitable for free cooling

Enthalpy sensors are compatible with Honeywell economizer systems

When used with an economizer, the enthalpy boundary curve is programmed via the controller

When the temperature and humidity are determined to be suitable based on the relationship to the boundary, the controller allows outside air for economizing

Dual enthalpy sensors in outside air and return switches the controllers to economizer mode of operation anytime the outside enthalpy is less than the return air enthalpy

The C7250 Mixed Air Sensor is Designed for Use as a 20K Input to a Controller for Mixed Air Temperature in Rooftop Packaged Air Conditioning Equipment

Plugs Directly into Wall Outlet

Lamp Plugs into Receptacle at Bottom of Winter Watchman Device

Useful When House is Unoccupied to Notify a Neighbor of a Temperature Drop So Heating Source Fault Can be Rectified before Freeze-Up Occurs

Not Precision Calibrated for Use as a Thermostat

Use in Intermittent Ignition Applications

Capable of Zone Control with Zone Valves

Circulator Zone Control with Zach and or Terminals on R8182D,E,H,J 8 Flame Failure During the Running Cycle Results in a 45 Second Attempt to Restart

If Unsuccessful, Safety Shut-Off Occurs, Requiring Manual Reset before Burner Can be Restarted

R8182D,E,F Mount Directly on Burner

R8182H,J Mount on 4 x 4 in Junction Box and Include 5 Foot (1.5 Meter) Armored Capillary with Remote Sensor

C554A Cadmium Sulfide Flame Detector and a 24 Volt AC Thermostat Required
