Sauna Controller

FUNCTIONS

The Sauna Controller block allows you to control and monitor your sauna. All conventional heaters are compatible (switched heaters and heaters that accept a 0-10V control signal).

The function block has a timer function, fan and drying control, as well as a safety shut down in case you forget to switch off the heater. You can also use door contacts with the sauna to alert you if the door has been left open and is wasting heat and energy!

The function block can also be used in the user interface, for control whilst on the move! It is important that when using this block that you observe the safety regulations of your country.

Icon Exclamation Mark LoxoneMake sure to select appropriate sensors for the heat in the sauna!
See here our sauna temperature sensor in the webshop.
An over temperature manual cutoff thermostat must also be installed!

BASIC SETUP

Connect the temperature sensor for the sauna to the input AI.

The outputs are for the various types of heaters, AQ for 0-10V analogue, Q1, Q2 and Q3 for stage L1, L2 and L3 heaters. If the heater is a single phase using Q1 we need to set the parameter M to 1.

Then connect the fan to the output Qf.
