Honeywell 2909 T678A 1015, TEMPATURE CONTROLLER T678A 1015.

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

The Honeywell 1015E002 is a 2-stage Temperature Controller with a 20' capillary. It's capable of controlling gas, oil and electric heaters of nonstandard size. The controller will not operate in conditions of low or negative pressure.

A Temperature Controller that offers a 100F to 1000F range and 0.1 percent accuracy for use with heating and industrial applications. The controller can be set for 2-stage operation (preheat and main on) using the factory preset jumper. Set points can be changed using the microprocessor self-contained reset circuit. Maintenance is easy due to front access copper heat sink, single screw terminal block and simple circuit design.

The T678A 1015 2-stage temperature controller regulates the temperature of a room or enclosure to a desired set point. A set point is recalled at power up and retained in memory even if power is lost. The output contacts may be wired to turn various loads on or off when the controller's set point is exceeded. The controller features two independently adjustable stages that can be set for different heating and cooling rates.

The Honeywell T678A 1015 2-Stage Temperature Controller precisely controls two heating and/or two cooling stages. The controller is easily programmed to turn a heat or cool source on and off at a selected set point determined by the user. Its two separate indicator lights tell you when the heating or cooling stage is on and when it has reached the desired temperature. The Honeywell 2-stage temperature controller offers precise control of greenhouse temperatures and has many applications including hydroponics, horticulture, green houses, and terrariums.

Honeywell High and low pressure control valves are field selectable, 2-way, normally closed secondary relief, temperature controller. Available in adjustable (manual) or fixed (two-stage), 100 F maximum temperature elimination and low pressure control. The two stage control valve is a special application that eliminates the need for an additional cold water tank when used with a primary tank containing anticorrosion properties.

Specially Designed for use with 3-stage air conditioning. Built-in -18f cut-off switch and -35f freeze protection for frozen conditions, preventing damage caused by burst crystals.

For commercial and residential heating/cooling applications, the Honeywell 2-Stage Thermostat is designed to offer maximum versatility at an affordable price. This product has a split-off switch box so it may be mounted in a convenient location and easily wired into your existing system.
