Switching off the Temperature Control Unit
The temperature control unit is switched off by pressing the ON/OFF but-
ton on the RT100 control system or by the timer, through a digital input or
an interface.
Depending on the temperature of the heat transfer medium, the shut-
down program runs as follows:
•
The pump and the control system are switched off. The RT100
control system will then be in standby mode and the message
OFF appears on the display.
•
The pump continues to run. The unit cools down until the tem-
perature of the heat transfer medium has reached the pro-
grammed coastdown temperature. On reaching this temperature,
the pump and the control system are effectively switched off. In
the case of pressurised water units, the pump then continues
running for a further few seconds in the opposite direction (pres-
sure release). The RT100 control system will then be in standby
mode and the message
OFF appears on the display.
Changing Consumers/Decommissioning
Before detaching the connecting lines, it is necessary to verify that the
temperature control unit is switched off and that all circuits are depressur-
ized (see the chapter "Switching off the Temperature Control Unit"). The
temperature control unit must be drained completely and stored in a dry
place at 10-40 °C when not in use. To restart the unit, proceed as in-
structed in the "Start-up" chapter.
Alarm Messages
The RT100 control system can display various error messages (warnings
and alarms). Attention must be paid to these error messages without fail.
Otherwise, malfunctions of / damage to the temperature control unit and
production downtimes may result.
Pressing the Alarm Reset button allows you to acknowledge/reset an
alarm (e.g. switching off the horn). Only after the malfunction has been
rectified can the alarm display be cleared by once again pressing the
Alarm Reset button.
The Alarm Reset button also allows manual acknowledgement of the au-
tomatic switchover (toggling) from consumer temperature control (or cas-
cade control)
Sn2 to outlet temperature control Sn1 in the event that
sensor Sn2 is defective or removed from the consumer.
