Bridge thermostats with simple touch control and differing Varioflex pump performance. PB models have a pressure/suction pump. PBD models have a more powerful pressure pump with eight stages which can be adjusted to the appropriate capacity requirements up to 1,1 bar with pump flow (pressure) up to a maximum 32 L/min and are able to control the temperature of deeper baths, up to 320 mm. Units have telescopic rods for baths with a width of 310 to 550 mm, ergonomic handles and pump connections on the back and the sides.

• Wide temperature range of up to 300 °C
• Heating capacity: 3,5 kW
• PowerAdapt means shorter heating-up periods and optimal performance without over-heating
• Choice of master or command version
• It is possible to upgrade from the master series to the command series at a later date

Master Thermostats: Proline Master thermostats have an easy to read green LED display with 0,01 °C resolution, simple three key operation with additional Tmax button and indicator lights for heating and cooling. SelfCheck assistant ensures user is automatically alerted to possible faults including over-temperature/overloading with visual and acoustic alarms. Units have two module sockets, which can be upgraded with RS232/485 interface, analogue or contact modules.

Selectable limitation of the setting range
Integrated external regulator in cascade connection
Flow temperature and correctional value limitation to achieve careful heating during operation under external control
Simple temperature probe calibration
Adjustable Start mode (automatic/manual)

Command Thermostats: Features of Proline Command thermostats are the same as Master series, and in addition units have high resolution, back-lit, graphic LCD display with actual values in 0,1/0,01 or 0,001 °C resolution. Data input is via either cursor keys or numerical soft keys. Units have multi-graphic display with clear text messages and graphical representation of sequential temperature curves and are menu driven in four languages (German, English, French and Spanish).

Fixed temperatures; user can select and edit eight temperatures
Real time clock in combination with timer function
Programmable control timer with storage for up to 150 temperature/time segments, each of which can be divided into five programmes
Integrated opto-decoupled RS232/485 interface as standard
Control head console can be detached and used as a remote control (up to 50 metres)

Max. flowrate/max. pressure:
PB: 25 L/min, 0,7 bar, suction 0,4 bar
PBD: 32 L/min, 1,1 bar
