62-3048—2

Fig. 21. Horizontal-body V2000 application.

Install controllers with external sensors in any position. The

sensor can easily be mounted in a position to measure and

control the room air temperature.

NOTE: When temperature of medium exceeds 190°F (88°C),

mount the MV100 horizontally.

WIRING (MV100 ONLY)

Wire the MV100 according to Fig. 18.

CAUTION

Equipment Damage Hazard.

Can short equipment circuitry.

Disconnect all power supplies before installation.

CAUTION

Equipment Damage Hazard.

Connecting improper voltage can damage the

device beyond repair.

Connect only 24 Vac or 24 Vdc to the MV100.

OPERATION

The T100 and MV100 Controllers contain temperature-

sensitive capsules that expand or contract in reaction to

temperature changes.

— When the capsule expands, pressure from the expand-

ing material closes the valve, preventing flow through

the radiation unit.

— When the capsule contracts, the valve opens and flow

resumes through the radiation unit.

T100

The T100 temperature-sensitive capsule expands when the

temperature rises above the setpoint.

MV100

When signalled by the thermostat, an electric element in the

MV100 heats the capsule causing it to expand.

NOTE: For normally open MV100 models, the capsule cools

when signalled by the thermostat.

SETTINGS AND ADJUSTMENTS

When installation is complete, rotate the setpoint dial to the

desired setting.

NOTE: The setpoint varies with the location of the sensor. A

floor level sensor controls at a setpoint different from

the wall level sensor.

Normally, correction of an overheating or underheating

condition requires only small changes. See Table 5 for dial

markings and corresponding temperature settings. After

changing the setting, allow the valve at least 30 minutes to

stabilize.
