RMS705B-1

The RMS705B-1 complements the range of Synco700 products as a freely configurable unit for

• control and supervisory functions in heating, ventilation and refrigeration plant
• non-standard applications

and, for this reason, offers no predefined standard applications

The RMS705B-1 is especially suited for the following functions:

• Connection of additional universal alarm inputs
• Adding free inputs for display and supervision
• Event logging (e.g. legionella function)
• Additional time programs (ON / OFF) for basic functions
• Calculation of enthalpy, enthalpy differential, absolute humidity, dewpoint and wet bulb temperature
• Logic function blocks for switching on / off depending on different conditions
• Lead / lag control of pumps, fans, motors, etc., with automatic changeover
• Step switch with linear, binary or flexible functionality

The RMS705B-1 supports the languages: English, German, French, Italian, Spanish, Portuguese, Dutch, Danish, Finnish, Norwegian, Swedish, Polish, Czech, Hungarian, Russian, Slovak, Bulgarian, Greek, Romanian, Slovenian, Serbian, Croatian, Turkish, Chinese.

Extension modules complement the switching and monitoring device and offer extra functions. They are attached to the controller via plug-in connectors. The extension modules do not operate autonomously. The operation of the device from commissioning to enduser operation can be done via the operator unit. Available extension modules:

• 1 universal module RMZ785
• 2 universal modules RMZ787
• 2 universal modules RMZ788

A total of 4 extension modules can simultaneously be used with the switching and monitoring device.
