VDH MC785-DF 2-stage thermostat

VDH MC 785-DF 2-stage thermostat with defrost and fan control building 

• The MC 785T-DF is a thermostat with two control stages, a defrost processor and fan control.
• The MC 785T-DF has a real time week clock. The clock can be used for real-time defrost and for automatical switching between day and night setpoint.
• The internal battery ensures that the clock will continue during power failure.
• The thermostat section can be programmed as cooling/heating or two stages of cooling or heating.
• The defrost is stopped on temperature with a limit on time. The defrost is started on an interval time, but can also be started by hand.
• The fan can be switched in automatic or continuous mode from the front.
• To the MC 785T-DF two control sensors can be connected, which makes it possible to control on the average of two sensors.
• Also two defrost sensors can be connected, where the defrost will first stop when both sensors reached the end-of-defrost temperature.
• The measured temperature and status of the controller can be read-out directly from the front.
• Operation and control has an easy and logic set-up.
• The MC 785T-DF has a digital input for external alarm and an analogue 0/+10 Vdc output for e.g. a P(I) function.
• The alarm relay switches if the measured temperature exceeds a preset alarm level.
• The MC 785T-DF Alfanet has a network connection for read-out and data logging on the Alfanet PC software.
• The standard MC 785T-DF does not have this connection.
• The MC 785T-DF is available for wall or panel mounting.
• The MC 785T-DF is supplied directly with 230Vac. Other supply voltages are possible on request.
