Turning off BT Thermostat does not turn of underlying cooler generic thermostat

[JP-Ellis]

Description

If the BT Thermostat is turned off, the underlying cooler thermostat remains active.

Set up

I have the following set up:

flowchart LR
    BT[Better Thermostat]
    GH[Generic Thermostat - Heat]
    GC[Generic Thermostat - Cool]
    BT --> GH --> SH(Switch - Heater)
    BT --> GC --> SC(Switch - Cooler)

Loading

Current Behaviour

I have noticed the following:

1. To begin, the BT and cool thermostats are both on.
2. I toggle the BT thermostat to off
3. The Generic thermostat (cool) remains on

Expected Behaviour

I would expect that:

1. To begin, the BT and cool thermostats are both on.
2. I toggle the BT thermostat to off
3. The Generic thermostat (cool) also is switched to off
