INSTALLATION INSTRUCTIONS

66-1184-01

Sensors for the SOLA Hydronic Control

APPLICATION

Both single and dual element 10KOhm resistive temperature

sensors are used with the Honeywell

SOLA Hydronic Boiler

Controls. Single element sensors provide only operation

temperatures to the

SOLA control. Dual element sensors may

provide both the operation and/or redundant limit

temperatures to the controller. Sensors may be used with

compatible Honeywell immersion wells.

FEATURES

• NTC resistive 10KOhm ± 1% at 25°C temperature

sensors.

•Sensor β=3950 for 25°C to 66°C (β=thermistor material

constant relative to its resistance versus temperature)

• Single element sensors for boiler Inlet, Header and

Outdoor temperature sensing functions.

• Dual element sensors for boiler Outlet, Domestic Hot

Water and Stack operation and limit temperature

sensing functions.

• 32003971-003 sensor kit contains sensor and hardware

for strap-on or outdoor mounting of sensor.

• Some models have Molex splice connectors for quick

field connection.

• Sensors may be used for either strap-on or insertion

type applications.

• Compatible immersion wells and accessories

available. Refer to Honeywell form number 68-0040 for

more information.

SENSORS FOR THE SOLA HYDRONIC CONTROL SPECIFICATIONS Honeywell offers a variety of sensor types for the SOLA Hydronic Control. Bare leadwires and Molex splice connectors are available. Sensors may be used for either insertion (into a well) or strap-on applications. Complementary parts such as immersion wells, mounting clamps and spring clips can be found in form number 680040, Immersion Wells and Compression Fittings. The immersion wells and other complementary parts must be ordered separately. Table 1.

SENSORS FOR THE SOLA HYDRONIC CONTROL GENERAL INFORMATION For detailed information regarding available immersion wells and complementary parts as well as complete selection, installation and other information, refer to form number 680040, Immersion Wells and Compression Fittings. Immersion Wells An immersion well consists of a metal tube, called the well shell, closed on one end. A well spud externally threaded to fit standard boiler tappings is welded or brazed on the open end.

SENSORS FOR THE SOLA HYDRONIC CONTROL boiler water of average temperature can circulate freely over the well. The tapping should be located to measure average system temperature. SENSOR WIRES BOILER IMPORTANT Always install the sensing element away from hot or cold water inlets, steam coils, and locations where the well pressure rating will be exceeded. 1. 2. 3. IMMERSION WELL Turn off all power. If the system is filled, drain it to a point below the boiler tapping or sensing element location.

General IMPORTANT Do not allow the tape to come into contact with the pipe. 4. When sensor installation is complete, check it as follows: 1. Secure insulation with duct tape or foil tape. See Fig. 3.
