Why God why is my boiler and thermostat control so fucking impossible to operate. It's sunny and hot here in the UK (for once) and I cannot turn off the good damn heating. I have three booklets of instructions (36 pages, 28 pages and 16 pages respectively) and all of them are proving to be useless. It's almost 30-fucking-°C inside the house and I am quite sure I am slowly melting. Why does this stuff have to be so complicated. When did instructions become biblical in proportions?
