Description
Applications
Thermostats & Hygrostats
193 HC
Powerstar Free Energy Band
Heating/Cooling Pneumatic
Room Thermostats
Designed for buildings with early morning heat require-
ments and mid-morning to afternoon cooling require-
ments, the Powerstar Free Energy Band Pneumatic Room
Thermostat two temperature thermostat controls valves,
damper actuators and mechanical heating and cooling
equipment. Providing energy management and occupant
comfort, the thermostat automatically reduces heating load
and increases cooling load.
Recommendation
2-pipe (dual 1-pipe): Use when a limited air capacity is
required to operate a single valve and/or actuator.
3-pipe (dual 2-pipe): Use for multiple valves and actua-
tors with or without high/low limiting controls which require
higher air capacities.
Providing proportional, dual output, dual set point, 2-pipe
(dual 1-pipe low air capacity) or 3-pipe (dual 2-pipe high air
capacity) pneumatic room temperature control, the 193 HC
Powerstart Free Energy Band Pneumatic Room Ther-
mostat creates a deadband so that no heating or cooling
occurs during the Free Energy Band.
