    Overview

    The Rinnai KWL503 Wireless Starter Kit is a convenient and user-friendly addition to your water heating system. The starter kit includes a remote control handset and a transceiver, allowing you to easily control your water heater from a distance. With a maximum of 4 controllers that can be used on this system, you can have multiple control points throughout your home. The remote control requires 2 x AAA batteries for operation. The LED control panel provides clear and easy-to-read information, including a signal strength indicator and a battery status indicator. The transfer button allows you to transfer control priority between the water controllers, giving you flexibility and convenience. The water heater indicator lets you know when the water heater is in operation and delivering hot water. The child lock feature ensures that the settings remain secure. The water temperature indicator shows the selected hot water temperature. It is important to note that if you require hotter than 50°C, an optional extra tempering valve is required for any water going to a bathroom or en suite, which is an additional charge provided by your plumber. With its practical features and ease of use, the Rinnai KWL503 Wireless Starter Kit is a valuable addition to your water heating system.
