Temperature controlled emergency opening is released only when the inside temperature exceeds the
temperature at which the emergency opening is set (Emergency opening - temperature). You can read the setting
as an actual figure in the display. The emergency opening is also active in case of power failure.
5.4.1.2.1 Emergency Opening Temperature
The temperature at which emergency opening is to open should be set directly on the adjustment button of the
emergency opening controller unit. The setting can be read in the display together with Temperature setpoint.
5.4.1.2.2 Warning at Emergency Temperature
The DOL 53X controller can give a warning which will flash in the display if Emergency opening setpoint is set
too high compared to Temperature setpoint (inside temperature). This is relevant particularly in houses with
batch production and a decreasing temperature curve. Here you must continuously make a downward
adjustment of Emergency opening setpoint. However, the too high setting may also have been created by
mistake.
The warning function can be connected and disconnected. It must be set at the number of degrees that the
Emergency opening setpoint is allowed to exceed the Temperature setpoint before the controller is to give a
warning.
5.4.1.2.3 Battery Alarm and Battery Voltage
The temperature controlled emergency opening function has a battery to ensure that the emergency opening
will operate in spite of power failure when the inside temperature exceeds the setting of the Emergency opening
setpoint.
You can read the current and the lowest measured voltages of the battery. These readings indicate when you
must change the battery or if a technical error has caused a battery alarm.
DOL 53X can generate an alarm when the battery which powers the emergency opening does not function.
