Honeywell Smartfit S Plan 24 Hour Control Pack Y4610A1028

The Smartfit S Plan is designed to provide timed independent control for both heating and domestic hot water circuits in fully pumped central heating systems. Time and temperature settings for both heating and hot water are set at the Room Unit, thus giving a single point of control. This revolutionary system is designed for ease of installation.

All control connections are either by two wire or plug and socket and are low voltage. Many Smartfit components are common to both Y and S Plans
and all controls are available as single items. Wiring for pump and boilers is the same for any control system. A central base unit provides simple low voltage plug in or two wire connection for all heating and hot water controls. Smartfit S Plan satisfies best practice of Buildings Regulations Part L1 when used in conjunction with radiator thermostats and an automatic bypass valve.
