[Feature Request] - Add Configurable Delay for Central Boiler Activation

[nagoz]

Description:

Currently, the versatile_thermostat module allows for the control of a central boiler through Home Assistant. However, there is a need to introduce a configurable delay when activating the boiler to prevent issues such as "water hammer" in the piping, which can occur if the boiler is turned on too frequently.

Proposed Enhancement:

Add Delay Parameter:

Introduce a new configuration parameter that allows users to set a delay (in seconds or minutes) before the boiler is activated.
This parameter should be easily adjustable through the user interface or configuration file.

Benefits:

Reduce maintenance costs related to "water hammer".
Extend the lifespan of the piping and boiler components.
Optimize energy usage and boiler activation cycles.
Conclusion:

This enhancement will allow versatile_thermostat users to better control the activation of their central boiler, reducing the risk of damage to the system and optimizing energy costs.

Hello, thank you for this proposal. Can you explain we, why adding a delay will reduce the "water hammer" effect.
For me, starting now or later will always starts and generate the "water hammer". No ?

I didn’t explain myself very well.
The issue I have is that when the valves close, water can still keep circulating until the circulation pump stops.
So, I would like the pump to stop as soon as the last thermostat no longer needs the circulator — meaning the circulator should stop first, and then the thermostats should close.

Similarly, when the first thermostat opens, if the circulator could start with a slight delay, it would prevent water from flowing while the valves are opening.

Hello, thanks for the explanation. It is more clear now and seems a legit request.
This is not so simple because, the boiler is controled with the activation state of the valve, so the valve should be to 0 BEFORE the central boiler will stop.

Does anyone have the same kind of requirements ? Please 👍 if you are interested.
