A Watts Water Technologies Company
Air Group Operation
In order to prevent heating and cooling
at the same time, this thermostat can
operate together with other thermostats on a
tekmarNet
system to form an air group.
In an air group, a heat-cool thermostat
is assigned as the air group master. The
air group master operates the cooling
and air heating equipment for the group.
The 532 can be set to be a member of
the air group.

Master
When operating as an air group, the air temperature readings of all the air group
member thermostats are communicated to the air group master thermostat and an
average temperature is determined.
When the air group master is in cooling operation, the air group member thermostats
do not operate the heating system for air heating. Once the cooling system shuts off,
heating is available if required.
Some air group master thermostats have the abilty to prevent radiant floor heating
while the air heating system is operating during mild outdoor temperatures. Once the
outdoor temperature falls below the first stage warm weather shut down setting, the
air group member thermostats are allowed to heat if required.
Schedules
Lowering the room temperature setting reduces the amount of fuel required to heat the
building, resulting in energy savings.
This thermostat can follow a programmable schedule in order to automatically lower the
room temperature setting. A schedule master such as a Timer 033 or a programmable
tekmarNet thermostat 552, 553, 554 or 557 is required in order to gain programmable
schedule functionality.
When operating on a programmable schedule, a or a is shown on the display.

Programmable schedule at occupied temperature.
Programmable schedule at unoccupied temperature.
When a programmable schedule is selected, there is a time delay for the temperature
in the room to change from the temperature to the temperature.
When a schedule is set, the thermostat uses Optimum Start to predict the heat up and
cool off rate of the room. The optimum start feature allows the room to reach the set
room temperature by the time set in the programmable schedule.
