Dry contact for thermostat
Setting and using method
Set desired temperature using Universal Input
n
Change a desired temperature using universal input value
: the voltage(DC 2.5 V~8.5 V) or resistance(2.5~8.5 kΩ) value of external controller or devices through
universal input port can be applied desired temperature value(18~30 °C).

• When this function is enabled, value of TEMP_SW is ignored.
• When using resistance type input, it possible to occur ±2 ℉(±1 ℃) tolerance by internal voltage source

2) Enable CN_WIND signal – Amount of wind flow(Low, Middle, High) signal enable
Notes
• Information of ‘OPER_SW’ is sensed only initial step by Dry contact module therefore , once the
configuration changed , Reset of Dry contact module is required.
• After power input or unit’s reset , wait 25~30 seconds(Display LED 10 times blinking) for unit
stabilization then Dry contact module will operate normally.
• Do not use desired temperature setting function when interlocking with thermostat.
