BUFFER

The algorithm is based on the readings from two temperature sensors. The device connected to the contact will be
enabled when the temperature of both sensors drops below the pre-set value. It will operate until the pre-set
temperature of the buffer bottom sensor is reached.
• Pre-set buffer top – the user may define the pre-set temperature.
• Pre-set buffer bottom – the user may define the pre-set temperature.
• Top sensor - the user may select the sensor.
• Bottom sensor - the user may select the sensor.

DHW BUFFER

The algorithm is based on the readings from two temperature sensors. The device connected to the contact will be
enabled if the temperature on any of the sensors drops below the set value by the value of hysteresis. After the pre-set
temperature of buffer top has been reached, the device will continue to work for the delay time defined by the user. It
will be disabled after the pre-set temperature of both sensors has been reached. It is also possible to set the operation of
this device based on a weekly program (described in detail in part XIII), which controls the set temperature of the upper
sensor. The user can select which sensor will function as the upper and lower sensor.
