2. Important information for your safety

The wave.com4 11 kW sauna controller has been manufactured

according to the applicable safety regulations. However, hazards

may arise during use. You should therefore adhere to the following

safetyinformationandthespecicwarningsintheinstallationand

operating instructions. Also observe the safety information for the

devices connected.

2.1. Intended use

The wave.com4 11 kW sauna controller is designed solely for oper-

ating and controlling the functions described in the technical data.

The sauna controller may only be used for operating and controlling

three heating circuits with a maximum output of 3.7 kW per heating

circuit.

When using the optional wave.com4 expansion board (WC4-H-PCB),

the maximum evaporator output is 3.0 kW.

According to EN 60335-2-53 sauna remote control units may only be

used to regulate and control a sauna heater that passes the cover test

according to paragraph 19.101. Alternatively, an appropriate safety

measure (e.g.: safety shutdown, door contact...) must be installed.

Any use exceeding this scope is considered improper use. Improper

use can result in damage to the product, severe injuries or death.

The warranty is void if the device is not used as intended.

3.4. Product features

The wave.com4 11 kW sauna controller features the following functions:

●Regulation of sauna heaters with a heating output of up to 11 kW.

●When an expansion board is installed, regulation of combined heaters with

a heating output of up to 11 kW and evaporator output of up to 3 kW.

●When a power booster is installed, the maximum power rating of 11 kW can

be increased.

●Option to connect external main switch

●Option to connect external light switch

●Switching and dimming a cabin light (up to 100 W bulb)

●Fan regulation (up to 100 W)

●Automatic heating time limit

The sauna controller shuts down automatically for safety reasons after the

maximum heating time (1 to 12 hours).

●Preset time function (1 to 24 hours)

●Acoustic signal for time interval (e.g: time to pour water on stones)

●Post-drying program

After operation in combined mode, the post-drying program starts automatically

to prevent mould or rot from forming in the sauna cabin. (3 setting options).

●Remote start function

●Eco mode

Eco mode ensures that the cabin temperature is the same after a break

(20, 40, 60 minutes).

●Overheat cut-out

The overheat cut-out is installed in the housing for the heater sensor. If a de-

fect causes the sauna heater to continue heating after reaching the preferred

temperature,theoverheatcut-outswitchesthesaunaheateroatatemper-

ature of around 139 °C.

EN

Instructions for installation and use p. 11/38

3.5. Sauna operating modes

Sauna mode

Dry heat is provided in sauna mode. The temperature in the cabin is high (80 to

100 °C). The humidity is low (no more than 10%).

Combined mode (optional – with expansion board)

In combined mode, the evaporator operates along with the heater. The temper-

ature in the sauna cabin is lower (around 40 to 65 °C) than in sauna mode, but

the relative humidity is much higher, ranging from 35% to 70%. The maximum

humidity that can be set depends on the temperature of the sauna. The higher

the sauna temperature, the lower the maximum humidity level that can be set

(see Fig. 1).

3.6. Sensor operating modes

The wave.com4 11 kW sauna controller can be operated with one, two or three

sensors.

Single sensor mode (F1)

Single sensor mode is the factory setting.

In single sensor mode, the sauna controller is operated with the heater sensor

with overheat cut-out only.

The sauna controller displays the actual temperature by default. The target

temperature is displayed while the setting is entered.

In single sensor mode, the maximum humidity that can be set (optional – with

expansion board) is based on the temperature above the heater and the humidity

is timed. Only the setpoint for the humidity (in % relative humidity) is shown on

the sauna controller display. The actual humidity in the sauna cabin when the

humidity is timed depends on the size of the cabin and the evaporator output,

andmaydierfromthesetpoint.

Instructions for installation and use p. 12/38

Two-sensor mode with humidity/temperature sensor (FTS2)

(optional – with expansion board)

In two-sensor mode with humidity/temperature sensor, the sauna controller

displays the temperature measured by the humidity/temperature sensor as the

actual temperature.

In two-sensor mode with humidity/temperature sensor, the evaporator is regulat-

ed according to the humidity level measured in the cabin. The sauna controller

displays the actual humidity (in % relative humidity) in the sauna cabin.

Two-sensor mode with bench sensor (F2)

(optional – with expansion board)

In two-sensor mode with bench sensor, a second temperature sensor (bench

sensor) is installed above the rear sauna bench. The sauna controller displays

the temperature measured by the bench sensor as the actual temperature.

In two-sensor mode with bench sensor, the humidity is timed. Only the setpoint

for the humidity (in % relative humidity) is shown on the sauna controller display.

The actual humidity in the sauna cabin when the humidity is timed depends on

thesizeofthecabinandtheevaporatoroutput,andmaydierfromthesetpoint.

Two-sensor mode with humidity sensor (WC4-H-H)

(optional – with expansion board)

In two-sensor mode with humidity sensor, the sauna controller displays the tem-

perature measured by the heater sensor as the actual temperature. The evap-

orator is regulated according to the humidity measured in the cabin. The sauna

controller displays the actual humidity (in % relative humidity) in the sauna cabin.

Three-sensor mode with bench sensor (F2) and humidity sensor (WC4-H-Hx)

(optional – with expansion board)

In three-sensor mode with bench sensor and humidity sensor, the sauna controller

displays the temperature measured by the bench sensor as the actual temperature.

In three-sensor mode, the evaporator is regulated according to the humidity

measured in the cabin. The sauna controller displays the actual humidity (in %

relative humidity) in the sauna cabin.

4. Installation

During installation observe the technical data; see Page 37:

4.1. Installing the power unit

See Fig. 2 on Page 14.

ATTENTION!

Damage to the unit

The sauna controller is resistant to splashing water, but direct contact with water

could still damage it.

●Install the sauna controller in a dry place where the maximum humidity will

not exceed 95%.

●When installed in the sauna cabin, the cable bushings must not point upwards!

●The sensors may only be connected using the sensor cables supplied

with the unit, which are heat-resistant up to 150 °C.

●The heater sensor cables may NOT be longer than 10 m.

●Outside the cabin, the sensor cables can be extended using cables

that are not temperature-resistant.

ATTENTION!

Interference can impair signal transmission

●Route all sensor cables separately from other mains cables and control cables.

●Protect cables with only one layer of insulation by using a conduit (double

insulation).
