Sauna controller

Configure and set up easily with Loxone Config

Functions

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

The module has a timer function, fan and drying control, as well as a safety shut down.

The block can also be used in the user interface, for control whilst on the move!

 

Make sure to select appropriate sensors for the heat in the sauna!
See here our sauna temperature sensor in the webshop.

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. 


You can now control the block in the user interface. The sauna on/off function (Tr input) can also be done through a switch on the wall, for example outside the sauna itself.

Overview

Inputs

Description

 
Tr

Trigger sauna

Turns the sauna on or off
T

Analogue input for desired target temperature

Set either with a virtual input connector or a timer switch
AI

Analogue temperature for actual temperature

Connect the sauna sensor to this
Tf

Trigger fan

Turns the fan on or off
Tc

Starts the hourglass timer

The output AQt shows the time counting down and Qta gives the timer's status, can set the time with parameter T, Qte pulses when the timer is finished
D

Door position sensor

Input for door contact (only shows the door state in the visualisation)
Ab

Bench temperature

Analogue input for bench temperature sensor
P

Input for presence detector

Connect a motion sensor to this input if the sauna has one
R

Reset

Turns all outputs off

Dis

Disable Disables all inputs
