Honeywell Sundial Y Plan Pack

Sundial Plan is the name that has been used for over 30 years by Honeywell to identify a grouping of control products which together provide a complete central heating temperature control system.

The main operating requirements of Sundial Plans are:

1. The controls should provide full independent temperature control of both living space and stored domestic hotwater.

2. If there is no demand for either living space or domestic hot water heating, the central heating boiler and pump must both be switched off.

The standard components of a Sundial plan are room and cylinder thermostats together with a motorised valve, or valves.

Y Plan

The Sundial 'Y' Plan is designed to provide independent temperature control of both heating and hot water circuits in fully pumped heating installations. This is accomplished by the use of a mid position valve. Time control may be provided by a programmer.

Y Plan contents:

• 1 x T6360B Room Thermostat
• 1 x L641A Cylinder Thermostat
• 1 x V4073A 22mm Mid-Position Valve

Please Note
Adding a programmer will ensure that the householders temperature needs are met at the times required.
Programmer is not included as standard
