Honeywell V100P Installation Instructions

DESCRIPTION
The V100P Radiator Valve is designed to automatically
control temperatures of one-pipe low pressure steam
radiators, convectors, or other heating units. Install the
V100P Radiator Valve with a T100 Thermostatic Control
and an SA123A (or equivalent) steam/air vent (see Fig. 1).
The Y100P includes the V100P Valve and the SA123A
Steam/Air Vent. V100P Radiator Valves are cast bronze,
with nickel plating. The working parts are designed as an
easily replaceable cartridge. A resilient seat disk provides
positive shut-off.

OPERATION
The V100P Radiator Valve works in conjunction with an
SA123A (or equivalent) steam/air vent (see Fig. 1).
During a call for heat, the valve opens, allowing air to
vent from the radiator. This, in turn, allows steam to flow
into the radiator. When the space temperature reaches
the setpoint, the valve closes, preventing air from
venting. When the valve is closed, the radiator cools.
The control has a modulating rather than an on/off
action to minimize room temperature changes.
