16 Operating Instructions Temperature Control Unit 90smart/150smart
NOTE
In the case of pressurised water units, the pressure release valve (Y8) closes at
5 °C above the coastdown temperature (max. 85 °C) and opens at the pro-
grammed coastdown temperature during the cooling process (only devices with
1K/2K).
Operation with Code/Password
In order to prevent the values that have already been set or programmed
from being unintentionally reset/adjusted, the use of a code/password is
urgently recommended. The code is defined in the parameter Code.
The RT70 control system has three password levels that are organised
hierarchically:
User password - Default 0000 (switched off)
Technician password - Default 0070
Service password - only for personnel trained by Regloplas
NOTE
It is strongly recommended that an operator password should be set up when
commissioning the temperature control unit.
Alarm Reset and Alarm History
Alarm Reset
If an alarm has been triggered, the signal horn can be switched off by
pressing the Alarm Reset button. After the malfunction has been reme-
died, the alarm can be reset by again pressing the Alarm Reset button.
Alarm History
If there is no alarm pending, the Alarm Reset button can be used to view
the alarm history.
Save/Reset of the Setting Values
The RT70 control system provides the facility to reload the factory set-
tings or user settings at any time by a simple procedure. Two different
new customer-specific settings can be loaded (user setting 1 and 2).
Changing Consumer/Decommissioning
Before detaching the connecting lines, it is necessary to verify that the
temperature control unit is turned off and that all circuits are depressur-
ised (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.
