Starting at OJ

We care about giving you the best start in your new job at OJ, which is why we provide you a detailed introduction programme usually the week before you start, so you know who will meet you on the first day and how the first weeks are going to be.

Form and function – combined in elegant high-quality design

Our room thermostats for electric underfloor heating are recognised for their ideal combination of form and function. They are just as easy to install and program as they are pleasing to the eye – and they handle even high-load applications with precise temperature control. However, no matter whether our thermostats are to be integrated in electrical outlets, flush-mounted, or wall-mounted, a thermostat from OJ will always be characterised by quality, reliability and attractive design.
