Once the body temperature rises over about 65 degrees or so, the glow plug is shut down, all the while the fuel pump and fan speeds are progressively increased until at full speed.
The heater runs in this state for quite a few minutes getting the internals nice and hot.

After running at full speed for a while, the heater transitions to the running state, and now obeys the desired setting being ewither a thermostat setting, or a fixed heat demand.
This happens about 5 minutes after the initial start was demanded:

To toggle from Thermostat or Fixed demand modes, hold the down key:

The changed operating mode is reflected in the units reported below the target icon. DegC for thermostat, Hz for fixed demand:

About a minute later the glow plug is un-powered and the heater then transitions to cooldown mode:

It stays in cooldown mode until the heat excahnger is observed to have dropped below 55 degC, at which pointit then returns to the initial idle state.
