b) The temperature control media must have a combustion point of ≥ 65 °C.
c) The overheat protection can, for instance, can be realized using a suitable fill level sensor or a suitable temper-
ature limiter.
d) Optional at the choice of the manufacturer.
Combined electronic low level and overtemperature protection
This temperature control unit has been equipped with an electronic overtemperature protection
and low-level protection. Instead of a mechanical float switch, temperature sensors are employed
on the surface of the heating coils. These sensors monitor overtemperature at this potential ignition
source, thus ensuring the controller regulates the heating coil temperatures below the critical tem-
perature (combustion point of the thermal fluid). An appropriate message is output via the
>Touchscreen< [88].
There is no longer a need for mechanical tools to set the trigger values of the overtemperature
protection. It is replaced by a software engineering tool. The threshold value for the overtempera-
ture protection can be set only if a code, randomly generated by “Pilot ONE”, is entered correctly. As
with the mechanical tool, accidental settings are thus prevented.
Low level protection
Low level protection is achieved via a pressure sensor in the fluid circuit. The pump ensures, togeth-
er with the thermal fluid, the requisite pressure at the pressure sensor. Air in the system (fill level
too low, inadequately vented) prevents the pressure from reaching value specified at the pressure
sensor. Temperature control and circulation are interrupted.
Overtemperature protection (for temperature control units with heating)
Mechanical tools are no longer required for setting the trip values for the overtemperature protec-
tion. A software tool is used instead. The threshold value for the overtemperature protection can be
set only if a code randomly generated by “Pilot ONE” beforehand is entered correctly. As with the
mechanical tool, accidental settings are thus prevented. The type of overtemperature protection
function and of low level protection depends on the temperature control unit.
Process safety
This type of overtemperature protection is driven by a desire for further protection of operator and
system. Protective devices typically disconnect all poles when reaching the overtemperature protec-

tion trigger value. This may result in more heat being fed into the process (e.g. exothermic reaction)
than the existing cooling machine is able to cool as the overtemperature protection trigger value is
usually set above the controller setpoint. Turning off the temperature control unit eliminates the
possibility to extract heat from the process. The temperature could therefore rise further and sys-
tem components could be heated up above their rated temperatures, e.g. could cause danger to life
and limb by rupture of the material or phase transitions from liquid to gaseous state. Reaching the
trigger value is recognized in the Process Safety mode by the controller at the overtemperature
protection, which then releases cooling. This mode requires the compressor to be set to Permanent-
ly ON ([System Settings] > [Power/ECO Settings] > [Compressor ON/OFF/AUTO] > [Permanently
ON]). Even if the temperature continues to rise, the cooling machine will use its maximum cooling
capacity to keep any further increase in temperature as low as possible. You must observe page 42
of section »Setting the overtemperature protection«.
1.4.3 Further protective devices
Emergency strategy – isolate the power supply!
To determine the type of switch or switch combination your temperature control unit is equipped

1.4.3.1 Power interruption
Following a power outage (or when switching on the temperature control unit), this function can be
used to determine how the temperature control unit is supposed to respond. This response can be
determined via “Pilot ONE”.
OFF/Standby (Default setting)
After turning the temperature control unit on, thermoregulation is started only after manual input.
ON / Temperature control active
After turning on the temperature control unit, thermoregulation is always started. An INFO appears
for a few seconds. This makes it possible to suppress the automatic start.
Power Failure Auto
If temperature control is active during a power outage, the process will automatically continue after
the power outage.
1.4.3.2 Alarm functions
An alarm is a system state that signals unfavorable process conditions. The temperature control unit
can be programmed so that the plant operator is warned when defined limit values are exceeded.
The response of the temperature control unit to an alarm can be determined. Possible responses
are: Switch off temperature control or control temperature to a safe setpoint (2nd setpoint).
1.4.3.3 Warning messages
Warning messages contain a message about the irregularity of the temperature control unit. These
messages have no further consequences. The plant operator evaluates the relevance of the message
and takes action where necessary.
