Power Supply Mounting Location Thermostat is suggested to be installed indoors, a place with around 1.5m height above the floor so that it can measure the average room temperature. It should be away from direct sunlight, any cover or any heat source, to avoid false signal for temperature control. CAUTION: Cut off the supply power at the circuit breaker or fuse before installation to avoid fire,

Note 2: Device Instance Number (Device ID) is automatically calculated as below. For example: Mac: 13, Loop ID: 1 => Device ID = 856 * 1000 + 1 * 200+ 13 = 856213 When the MAC address is changed via configuration menu, the Device ID is automatically recalculated to avoid network ID conflict. As a property of Device Object, Device ID value is writable via BACnet between 0 and 4194302. Once the Device ID is changed via BACnet, Device ID automatic calculation mentioned above is ineffective. When the thermostat front plate is flipped, the EOL resistor DIP switch is seen on the upper right side of...
