Sauna Controller with Evaporator

FUNCTIONS

The Sauna controller with evaporator 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 evaporator can be switched on and off but can also be controlled with an analogue 0-10V 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!

You can choose between different operating modes such as steam sauna, Finnish sauna, herbal sauna etc.

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.

Make 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, and then connect the humidity sensor to AIh.

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.

Where you connect the evaporator to depends on the control type. If it is 0-10V analogue then connect to AQv, if it is digital on/off then connect to Qv.

Finally 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.

When the block is in a manual mode the target values for temperature (input T) and humidity (input H) are used.

If the evaporator has a water shortage sensor this can be connected to the input LW so an alert can be triggered. Also if the input LW is triggered and has a value of 1 (digital input) the evaporator will no longer turn on.
