Honeywell 2909 T678A 1015, TEMPATURE CONTROLLER T678A 1015 85267090711 .

TEMP CONTROL 2-STAGE 0-100F 20' CAP

This 2-stage temperature controller is designed for use with high-wattage appliances to help protect your home heating system against overcurrent. This dial temperature controller has a range of 0 to 100°F, and a 20 amps capacity.

The Honeywell T678A 1015 2-stage compressor temperature control is designed for use in air conditioning and refrigeration systems. The 1015 is an electrically actuated, single-space, completely potted control with a double solenoid valve, normally closed contact and thermistor..

Stress-free temperature control. Honeywell temperature control units operate at a constant temperature of 0°F to 100°F (–17.8°C to 38°C), ideal for storing wine, home brew, or other food and beverage products. Contains 2 independent thermostats for each stage which feed back to a common microprocessor that manages both stages. Also includes an on-board stackable compartment heater that can be programmed separately from the stages."

The T678A1015 is the smallest controller Honeywell makes, for outdoor use only. It will only modulate a 2-stage compressor or heat pump (CRN 12 or BPV 15) with a capacity of 2-tons or less. This unit can be mounted on the compressor, but will still require an extension cord. The wiring harness is 22-gauge wire and has a 20' lead wire.

The Honeywell T678A 1015 (formerly the Senville B1002) features a platinum thermal sensor to provide two-stage temperature control. The electronic thermostat 1015 includes a front-access terminal block for easy wiring.

The Honeywell T678A 2-stage residential furnace temperature controller for 2 stage blowers features the ability to control duct static pressure, resulting in constant and uniform heat flow thru out the house.

The Honeywell T678A1015 may be used in a variety of refrigeration applications where precise temperature control is critical. Its two-stage operation offers flexibility to meet most application requirements. A Solid state control provides enhanced circuit reliability and unmatched accuracy. In addition, the T678A1015 is available with a factory mounted auxiliary cooling coil for when condensing unit shunt pump back up is desired.
