FAN OPTIONS
Calm dMEV DC 100 (S) Т fans are equipped with a turn-off delay timer. The unit operates at the set constant speed.
VT models are equipped with a cord-operated switch.
The fan switches to the intensive mode upon control voltage application to input terminal LT by an external switch (e.g.
indoor light switch). Upon control voltage removal the fan continues to operate in the intensive mode for the period of time
set by means of a DIP switch.
Calm dMEV DC 100 SELV fan is rated for connection to safe 12 V/50 Hz power mains.
Calm dMEV DC 100 (S) H fans are equipped with a turn-off and turn-on delay timer when the humidity level is exceeded.
The fan switches to the intensive mode upon control voltage application to input terminal LT by an external switch (e.g.
indoor light switch). Upon control voltage removal the fan continues to operate in the intensive mode for the period of time
set by means of a DIP switch. The S (H) models are equipped with a cord-operated switch.
DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT
OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD.
FAN OPERATION SETUP
THE TIMER CIRCUIT IS LIVE.
MAKE SURE THE FAN IS DISCONNECTED FROM POWER SUPPLY.
