7.4 Setting the warm weather shutdown
(WWSD) temperature
In addition to the outdoor temperature, your Logamatic 2107 controls considers
the ability of the building to store heat (called the "adjusted outdoor temperature"
below) and automatically delays changing over between summer and winter
mode. The changeover takes place regardless of the actual time of year.
The automatic summer / winter changeover only applies to heating zones that
are in automatic mode with timer.
Summer mode
The heating mode will be switched off after a delay which depends on the
building’s capacity to store heat and its thermal insulation if the "adjusted
outdoor temperature" exceeds the changeover threshold (factory default 63°F
(17°C)).
Winter mode
The heating is restarted if the "adjusted outdoor temperature" falls below the
factory-set changeover threshold of 63°F (17°C).
