Fig. 21.
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.
Fig. 22. MV100 internal schematic and wiring connections.
OPERATION
The T100 and MV100 Controllers contain temperature- sensitive capsules that expand or contract in reaction to temperature changes.
WIRING (MV100 ONLY)
Wire the MV100 according to Fig. 18.
CAUTION
Equipment Damage Hazard.
Can short equipment circuitry.
Disconnect all power supplies before installation.
—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.

CAUTION
Equipment Damage Hazard.
Connecting improper voltage can damage the device beyond repair.
Connect only 24 Vac or 24 Vdc to the MV100.
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.
