1.2. Unique Control Features
The controller is optimised for water cooling laser systems with bypass regulation.
After re-starting (starting point below/above the set value) maximum heating/cooling power will be
used to reach the accordant value.
On the one hand, the analysis of the flow rate sensors is monitored on the front panel display ( with
time delay for starting), on the other hand the signal (for release) would be send directly to the digital
output (“1” = release)

1.4. Sheme of control elements
The operational mode is indicated by lighting of the green LED. If a fault occurs, the
red LED will light. It depends to the fault and the adjusted parameters whether the
chiller discontinues operating. The beeper can be disabled by pressing the mute-
button (←). The error messages are self-explanatory by pressing the info-button
(→). The appeard fault can be accepted by pressing the Quit-button (↓). If remote
start is enabled, the fault can only be accepted by the remote start signal. The
chiller restarts autonomously when the green LED lights.

2.2.2 Parameter Description Language
Choose the required language for display. Fill
This mode is required to fill and to drain the unit: Starting the filling mode is only possible if the controller is switched off („starting mode“ = key) or remote start („starting mode” = line) is disabled. If the fill mode is enabled, it can be started by switching off the chiller and on again. While the filling mode is active, no alarm messages are monitored (only for a defined period System function/Advanced/Long term rejection).
Water level/ Switch off output
This allows the disabling of the outputs at water level alarm to be prohibited. In this case, simultaneous operation together with the flow alarm will be prevented (i.e. Switch off output = YES) => at water alarm, no flow alarm will be given.
Level monitor Monitors the water level via bar on the display.

Read out the hours of operation. Starting mode
The controller can switched on or off using either the UP-button (↑) on the front panel, the remote start input or the start flag (via RS232 – connector). If the remote start input is used to enable the outputs, then the controller is always on. Using the starting mode line, the chiller will start as soon as voltage is enable.
Temperature scale The unit can be switched between Fahrenheit and Celsius. Despite changing this unit, the parameter and set value and adjustment range remain the same. Only the display shows °F!

6. F. A. Q. Please try to solve your problems with this F.A.Q. bevor contacting TERMOTEK. My computer does not communicate with the TERMOTEK chiller via the visualisation software
1. Check the connection between the chiller (RS232 – connector and the computer. 2. Check that the computer uses the correct interface (normally COM 1 or COM 2). These must
be adjusted in the visualisation software.
3. The TERMOTEK chiller is delivered with an interface speed of 38,400 Baud normally, the computer is set to 9,600 Baud mostly. You can change the speed via system control as follows:

You can change the interface speed at the chiller at system functions/baudrate. TERMOTEK suggest to change the speed at your computer.
I want to use my own software to enable/disable the chiller. Which command have I to use?
IOs: Element Offset Length/Bit Description Unit/Selections SysFkt_DI_Extern 1 Bit 0 Remote start 0 = OFF, 1 = ON
Two parameters for the output of the water temperature are available (<<Wasserkrei_Wassertemp‐AI‐TVorlaufRohEx>> at IOs and <<Wasserkrei_Wassertemp_AI_TVorlaufEx>> at flags) Both transmit a reasonnable value. What is the difference?
<<Wasserkrei_Wassertemp_AI_TVorlaufEx>> is eventually admit with an additional ajustment value. Calibrations will affect then.
We want to read all warnings, errors and alarms. How?
Read these via <<STAT_message>>. See chapter 5 for a description of this parameter.
