  • Page 19: Materials

    The pump connections on the unit are fitted with M16 x 1 thread. The Varioflex pump operates short-term up to viscosity of 150 mm²/s. In the closed-loop control mode 50 mm²/s should not be exceeded. The temperature control is the best with 30 mm²/s and lower viscosity. For operation as a circulating thermostat with an external load, the highest possible power level is practicable to maintain the temperature difference low, among other things also with higher temperatures in conjunction with oils as heat transfer liquid.

Furthermore, the pump level and the behavior of the switching outputs can be defined. Five temperature/time programs are provided for free programming. Each program consists of a number of temperature/time segments.
  • Page 68  Each program begins with the segment "Start". It defines at which temperature Segment 1 is to continue the program. It is not possible to specify a time for the Start segment. For thermostats without cooling ability, the start temperature must be selected higher than the bath temperature, which prevails before the program start.
