
Tap on the “Start” touchbutton.

Confirm the start of temperature control by tapping on “OK”.
The correct selection will be displayed graphically and temperature control will start immediate-
ly. If tapping on “OK” is not correct, it will be displayed graphically for 2 seconds. Then the dis-
play will return to the “Home” screen again. Try starting the thermoregulation again.

Tap on the keypad symbol next to “T
Setpoint
”.

Enter the new setpoint of 35 °C, using the number keypad that appears.

Confirm your choice by tapping on “OK”.

Open the upstream cooling water hand valve.

Finish the thermoregulation once the flow temperature has reached 40 °C.

Close the upstream cooling water hand valve.
4.3.2 Cooling water connection II
Valid for Unistat T305w HT, T320w HT, T330w HT, T340w HT
Use of unsuitable/defective hoses and/or hose connections
INJURIES

Thermal fluid

Use appropriate hoses and/or hose connections.

Check periodically for leaks and the quality of the hose and hose connections and take suitable
measures (replace) as required.

Isolate and protect temperature control hoses against contact/mechanical load.

Cooling water

Reinforced hoses must be used to satisfy tougher safety requirements.

Shut off the cooling water supply to the temperature control unit even for shorter downtimes
(e.g. overnight).
The T3xxw HT series is equipped with a cooling water connection with controlled cooling water
consumption. These temperature control units not only enable the implementation of positive
temperature gradients (e.g. setpoint step- changes from 20 °C to 150 °C) but also negative temper a-
ture gradients (e.g. setpoint step- changes from 150 °C to 20 °C). The T300w HT series is equipped
with a cooling capacity controller, which regulates the water outlet temperature to a level at which
calcification usually cannot take place (max. 60 °C). Activation of the cooling water release (as in the
above Section »Cooling water connection I« ) is not necessary!
PROCEDURE

Observe the permissible water entry temperature, see data sheet from page 89 in Section
»Annex« .

Observe the permissible water pressure, see data sheet from page 89 in Section »Annex« .

Only use suitable and temperature-stable hoses (e.g. reinforced hoses) and screw connections.
4.4 Filling, venting, degassing and draining
The illustration “Wiring diagram” can be found on page 89 in section
»Annex«
.
4.4.1 Externally closed application
Operating an externally closed system with >Isolating sleeve< [27] installed
BURSTING DUE TO OVERPRESSURE DURING TEMPERATURE CONTROL.
 Shut down the temperature control unit immediately.

Allow the thermal fluid to cool to room temperature.

Prior to starting up the temperature control unit with an externally closed system, remove the
>Isolating sleeve<
[27] (see page 24, in section
»Mounting/removing the isolating sleeve (op-
tional)« ).

Open all valves, in case of standard devices the >Venting valve expansion vessel< [21] by turn-
ing them anti- clockwise (turn 90° left as far as it will go).
