➜ Maximum deviations between the
patient’s temperature and the water
temperature during heating/cooling
have been exceeded
◗ The pumps of the corresponding circuit
stop.
➜ You can keep the water circuit running
(if neccessary) by continuously
pressing the corresponding Circuit
Start/Stop key.
➜ You may adjust the values for the

➜ Excess temperature,
Defective temperature control
◗ The pumps of the corresponding circuit
stop.
➜ Wait a for short time until the
temperature stabilizes at its set
temperature, restart the pumps.

suitable for an interim period and if no
