The circuit essentially consists of the following components:
Bath containing heat transfer liquid

Heater for heating the heat transfer liquid

Refrigerating machine for cooling the heat transfer liquid

You can display a hydraulic diagram of the circulation thermostats by
touching the [Hydraulic diagram] tile on the Command Touch remote con-
trol unit. You can tap individual components on this diagram to open the
submenu for the selected components directly. This function is not available
for the bath thermostats.
The bath thermostat is fitted with a variopump (pressure pump) for internal
bath circulation. The pump can be set to one of 8 pump levels (may be fewer
depending on the device) to optimize bath circulation, noise emissions and
mechanical heat input.
The automatic SteadyFlow function for the pump motor allows you to circu-
late high-viscosity heat transfer liquids at the same flow rate as low-viscosity
heat transfer liquids.
The variopump can operate briefly at a maximum viscosity of 150 mm²/s.
However, 50 mm²/s should not be exceeded during regular operation. The
ideal temperature controller setting is 30 mm²/s or lower.
The circulation thermostat is fitted with a powerful vario flex pump (pres-
sure-suction pump) for controlling the temperature of the consuming unit
effectively. The pump can be set to one of 8 pump levels (may be fewer
depending on the device) to optimize the output, conveyance pressure, noise
emissions and mechanical heat input.
The automatic SteadyFlow function for the pump motor allows you to circu-
late high-viscosity heat transfer liquids at the same flow rate as low-viscosity
heat transfer liquids.
The vario flex pump can operate briefly at a maximum viscosity of
150 mm²/s. However, 50 mm²/s should not be exceeded during regular
operation. The ideal temperature controller setting is 30 mm²/s or lower.
All heating bath thermostats and heating circulation thermostats are fitted
with a cooling coil for internal bath cooling as standard.
A cooling source such as a fresh water supply can be connected to the

cooling coil connection sockets.
See Ä Table 38 "Cooling water data" on page 134 for information on

inner hose diameters.
The bath temperature of the thermostat can be decreased to approxi-

mately 5 °C above the temperature of the cooling water (without an
external consuming unit).
The LCZ 9771 cooling water valve (with LiBus triggering) available as an

accessory only opens the cooling water supply when cooling is required.
