Overview
The Honeywell Sundial Pack is ideal for adding a room thermostat and a cylinder thermostat to a traditional system. In a stored hot water heating system which has no room thermostat or cylinder thermostat, the existing wiring can be used to provide boiler interlock by fitting Sundial RF2 Pack 3. This has a full programmer with independent heating and hot water and a built-in wireless transceiver to enable the wireless room thermostat and cylinder thermostat to maintain the traditional layout of separate time control and thermostats. It can also be used on new systems. Because the thermostats and the programmer communicate, energy-saving and operating benefits are also enabled.
