The Drayton Twinzone 86 Control Pack delivers a complete, hardwired regulatory solution for conventional central heating systems, allowing for the independent management of space heating and domestic hot water. Central to this kit is the intuitive LP522 programmer, which enables users to define distinct operating schedules to match their daily routines, thereby eliminating redundant fuel consumption. The system relies on two robust 22mm motorised zone valves to physically isolate the hydronic circuits. This mechanical separation ensures that the boiler only fires when there is a specific demand from either the ambient room thermostat or the hot water cylinder, vastly improving the overall thermal efficiency of the property.

Designed with straightforward installation in mind, the package includes an LWC1 wiring centre which acts as a consolidated junction for all electrical components, severely reducing complex routing errors on site. The provided RTS1 room thermostat and HTS3 cylinder thermostat are highly responsive, communicating precise temperature data back to the central programmer. By offering independent S-plan style control over separate zones, this British Gas approved suite provides professional installers with a robust, fit-and-forget mechanism to upgrade existing domestic heating infrastructure.

Q: What size pipework do the motorised valves accommodate?
A: The included 2-port motorised valves are designed for standard 22mm copper pipework.

Q: Does this pack allow heating and hot water to run independently?
A: Yes, the twin-zone configuration provides completely separate control over hot water and central heating circuits.

Q: Is a wiring centre included to manage the electrical connections?
A: The pack contains a dedicated LWC1 wiring centre to facilitate organized and safe electrical termination.

Q: Once installed, does the system require frequent recalibration?
A: No, once the thermostats and programmer are set, no further mechanical user adjustment is necessary.
