Application
TH 192 DN and DNV thermostats provide day-to-night (or weekend) temperature
setback to control pneumatic valve and damper actuators in heating and cooling
applications (Figure 1) such as air conditioners, space heaters, unit ventilators, and air
volume controllers.
The day-night thermostat is particularly useful in locations where all rooms in a zone are
not vacated at the same time. Using time clocks on evenings and weekends to reset the
control system to the night mode ensures optimum energy management. When a zone
is operating in maximum economy mode at night, an occupant can reset an individual
space to day temperature by switching a manual override. During night control, the TH
192 DNV provides a separate output signal (full air supply) which allows ventilation to
occur.
TH 192 DN and DNV thermostats maintain maximum economy and occupant comfort
automatically as a day progresses from the day time setpoint (65F to 68F [18C to
20C]) to the night time setpoint (55F to 60F [13C to 16C]). The thermostats are
available with covers that conceal or expose the setpoint adjustment dials.
