The company’s wireless sensors are available in a variety of form factors (e.g. zone, outdoor, duct) and for measuring different environmental variables (e.g. temperature, humidity, electricity/gas/water, voltage). The sensors are typically battery-powered with a life of 3 to 8 years, depending on transmission intervals. Optionally, sensors can be line-powered, using a small switching power supply that fits into a standard gang box. When a sensor detects the presence of a power supply, it will automatically also function as a repeater/router.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
