Controller operations
Manual operation
In manual operation, the user manually controls the settings of the
installation. The last setting remains active until the user changes it or
until the schedule timer forces another setting (refer to "Schedule
timer operation" on page 7).
As the controller can be used for a wide variety of installations, it is
possible to select a function which is not available on your
installation. In that case the message

Temperature range for heating: 77°F to 131°F (25°C to 55°C)
The temperature for heating can be set as low as 59°F
(15°C) (see "Field settings" on page 11). However, the
temperature for heating should only be set lower than 77°F
(25°C) during commissioning of the installation. When set
lower than 77°F (25°C), only the backup heater will operate.
In order to avoid overheating, space heating is not operable
when the outdoor ambient temperature rises above a certain
temperature (as set through field setting [4-02], refer to "Field
settings" on page 11).

Temperature range for cooling: 41°F to 72°F (5°C to 22°C)
CAUTION
The actual operation range depends on the values set on
field setting [9].
These values shall be determined based on the
application.

This means that the controller calculates the water
temperature set point based on the outdoor temperature.
In this case, instead of showing the water temperature
set point, the controller shows the "shift value" which
can be set by the user. This shift value is the
temperature difference between the temperature set
point calculated by the controller and the real set point.
E.g. a positive shift value means that the real
temperature set point will be higher than the calculated
set point.
