• Move the DIP Switch S2 as described in the ‘Dip Switch S2’ table above.
• Connect the temperature sensor to S4, S5 terminals.
• Reconnect the power (24vac).
• Make sure the display reading is that of the external sensor
• The length of the cable needed for the external sensor is 100 feet (30 meters). Standard cable may be used.
• If a longer distance is needed, then the cable MUST be shielded.
• There is a wide range of sensors available for different applications, ex: ducts, rooms, etc.
• There also exists an option for averaging the temperature.
• For details please contact our technical support line or visit our web site
