Dear users!
Water thermostat TW-2.03 is simple and reliable device. We ask you to consider technical
requirement for exploitation to provide the use of the equipment without problems for a long
period of time.
Water bath TW-2.03 is composed of the plastic water tank with the transparent lid and
control block. The control block has LED displays and control buttons on top. Control block
should be placed on the water tank and fixed with screw. On the bottom side of the control
block heater and water pump are situated. On the back side of the control block two pipes
are situated for connecting the water thermostat to an outer contour and maintaining the
temperature in the outer contour same as in the tank.
The device is designed to maintain the desired temperature regime with high level of
accuracy. This device is fully controlled by the microprocessor system with memory
independent from the source of energy.
