Function description
OPERATION MANUAL Chapter 3
Unistat® V2.0.0en/09.06.16//15.09
- Always adjust the inside diameter of temperature control hoses to the pump connections.
- The viscosity of the thermal fluid determines the pressure drop and affects the tempera-
ture control results, particularly at low operating temperatures.
- Too small connectors and couplers and valves can generate significant flow resistance.
Your application will therefore be slower to reach its design temperature.
▪ Basically, you should only use the thermal fluids recommended by the manufacturer and only
within the usable temperature and pressure range.
▪ With temperature control close to the boiling temperature of the thermal fluid, the application
should be roughly at the same height or below the temperature control unit.
▪ Fill the temperature control unit slowly, carefully and evenly. Wear the necessary personal pro-
tective equipment, such as goggles, heat-proof and chemicals-resistant gloves, etc.
▪ After filling and setting all the requisite parameters, the temperature control circuit must be
vented. This is required to ensure trouble-free operation of the temperature control unit and
hence your application.
For water-cooled temperature control units, please take the cooling water temperature necessary
for perfect operation and the required differential pressure from the data sheet from page 96
onward in the Section »Annex«.
3.4 “Pilot ONE®” controller
Figure »”Unistat Control ONE” and “Pilot ONE”« are shown on page 6.
The basic version of the "Pilot ONE" (Basic) can be upgraded in two stages (from Basic to Exklusiv
and from Exklusiv to Professional or from Exklusiv to Professional with DV-E-grade).
