Transform the way you service your HVAC customers! Quicker installation time with our groundbreaking water probe! Receive timely notifications by text and email! Customer service and retention at its core. The AC SpeedStick is a UL rated water switch commonly used in HVAC equipment. The AC Speedstick water switch shuts down the air handler when water level rises in the air handler drain pan. Water Probe – our unique water probe affixes in either of the condensation outlets on the back of the air handler. No need to remove air handler cowling for installation, dramatically reducing installation time. The water probe will trip the switch if water is detected for 10 seconds. The switch will resume normal operation when water is not detected for 10 seconds. The water probe also has 4’ lead to fit up to 3-ton air handlers. WIFI feature – During installation, the installer can utilize the optional Wi-Fi feature if Wi-Fi is available. With the WIFI feature enabled, if the switch is tripped, it will automatically notify the installer, and any desired parties. The AC Speedstick app is necessary for connecting the switch to the Wi-Fi. Wiring – the 4 wires in and out of the switch match most OEMs (black, red, green, white). Simple wiring means easier wiring. LED indicators – the green/red LED light indicates system is tripped or system is working. The blue LED light will flash during Wi-Fi connection and become solid blue when connected. Voltage – switch is rated for 120V or 240V

OnDevice is a local-first AI studio for iPhone. Run compatible language, vision, speech, and image models on your device. Browse models and choose what to download. Model size, memory use, and speed depend on your hardware. CHAT AND CREATE Ask questions, write, work with code, save snippets, and export conversations. Use camera or photo input with a compatible vision model, or use built-in OCR without downloading a vision model. Voice conversations use local Apple speech by default, with optional downloadable neural voices. Compatible image models support local image generation, which can be restricted with a parental PIN. YOU CHOOSE THE CONNECTIONS Local inference uses installed models. Network features are optional: model discovery and downloads, web search, paired Mac tools, a local API, and iCloud sync. Web providers may receive the queries or content you choose to send and may require their own API account. No app account is required for local use; there is no analytics SDK. REQUIREMENTS Requires iOS 18 or later. Downloadable models need storage and sufficient available memory. The app may pause or refuse heavy workloads when the device is too hot or memory is low. Model compatibility and performance vary by device.
