Optimisation Functions; Locking The Interface - Honeywell Y6H920RW4026 User Manual

Heating optimisation functions
Your T6/T6R Smart Thermostat has several heating optimisation functions. These
functions aim to save energy while making you as comfortable as possible.
Configure these options via the OPTIMISE menu on your Thermostat.
• Optimum Start
Over time, the Thermostat learns how long it takes your system to
reach the temperature you want. It turns on the heating or cooling
system earlier to make sure you're comfortable at the time you expect.
The Thermostat displays
• Optimum Stop
Saves energy and money by switching off a little bit earlier than the normal
programmed time. If your home is up to temperature, you will not notice the
effect on the temperature, but you will see a difference in your fuel bill.
• Delayed Start
Saves energy by slightly delaying the start of heating depending on the difference
between the programmed temperature and the actual room temperature.

Locking the interface

Your T6/T6R Smart Thermostat has a lock function, which can
restrict access to the Thermostat interface in two levels:
• PARTIAL: Allows changing the setpoint temperature only
• FULL: Restricts all access to the Thermostat interface
When the function is activated a PIN is given to unlock
the thermostat - take note of the PIN.
when it turns the system on early.
