Hydra 798 Iss.10 – 04/18
To reset the heater or cooler, the condition must be removed, that is the temperature must be restored to the
correct value by either waiting for the temperature to normalise, or by resetting the controller to a more suitable
value. The controller will need to be reset manually, even if the controller is switched off, it will still power up again
in the alarm condition until reset.
To reset the controller, ensure the temperature for both over and under temperature is safe then press both the
PAGE button and the SCROLL button simultaneously. The scrolling warning display will disappear and the illuminated
beacon light up.
