Honeywell Sundial RF2 Pack 4

The Sundial Heating packs from Honeywell are all-in-one control packs for your central heating and hot water system. This pack is ideal for adding a hot water timer and cylinder thermostat to new or existing control systems.

With battery powered operation and a clear backlit digital display, the Sundial Pack 4 is a heating control solution that doesn't require any wiring with the installation.

In a stored hot water heating system which has no cylinder thermostat the existing wiring can be used to provide Boiler Interlock by fitting Sundial RF2 Pack 4. This has a timer with a built in wireless transceiver to enable the cylinder thermostat, maintaining the traditional layout of separate time control and thermostats. It can also be used on new systems. Ideal for systems controlled by heating only programmable thermostats or where a hot water cylinder is being added to an existing heating system.
Because the sensor and the timer communicates, energy saving and operating benefits are also enabled:

Cylinder sensor controlled from the programmer.
