Note: In pressurised water units, the pressure relief valve closes 5 °C above the run-out temperature value, i.e. at max.
85 °C, and opens at the programmed run-out temperature during the cooling process.
ALARM RESET key
Functions:
Manual reset of the alarm relay (e.g. switching off a horn). Once the malfunction has been corrected, the alarm
–
display can be switched off by pressing this key once again.
Manual acknowledgment of automatic switchover from consumer temperature control or cascade control to
–
outlet temperature control in the event of defective or missing S2 sensor in the consumer.
SP key
Switchover from set-point value 1 (SP1) to set-point value (SP2) and vice versa.
Note: Set-point value switchover is possible only when no malfunction is present.
Operation with Code
To prevent the set or programmed values from being changed inadvertently, we strongly recommend the use of a
code.
There are four codes to choose from:
– Input value code
– Set-point value code
– User setting 1 code
– User setting 2 code
Factory setting code 0: The programmed values are not protected.
For programming, see RT50 Programming Instructions, Section 7.2, P 15.
Product-specific settings may not be changed, e.g. max. temperature.
Save/Reset to factory or user settings
The RT50 control system allows the user to reload the factory setting easily and at any time.
Reset factory setting: Code = 185. The factory setting is reloaded when this level is left. (The values saved under User
settings 1 and 2, including their codes, are overwritten.) Two different customer-specific settings (User settings 1 and
2) can be reloaded in the same manner.
For Programming, see RT50 Programming Instructions, Section 7.2, P 14.
