Easy-to-Use digital Sauna Controls :

Effortlessly control the temperature of your sauna with ease.
Sauna control panel consists of timer and thermostat in one unit to control sauna heaters operation. Sauna timer counts down the time and sauna thermostat controls the temperature. For safety in use at home sauna, the maximum recommended sauna temperature should not be higher than 131 deg. Fahrenheit ( 55C ) for infrared sauna and 194 deg. Fahrenheit ( 90C ) for traditional, dry sauna, while the maximum time should not exceed 60 minutes. For commercial applications the timer limits and the temperature preset and pre-heat limits can be customized.

Sauna Control Operation

Download controller specifications

SD-4PB is a digital temperature and time sauna controller designed for Heating and/or Cooling.
It has an internal, accurate, programmable thermostat processor, that is self-calibrating and does not require any maintenance or adjustments.
The internal, programmable, digital timer allows the user to set the thermostat to operate for a preset period of time, depending upon the model; in seconds, minutes, hours or days.
While the timer is running, the thermostat controls the on-board relays.
Standard models have two on-board, high power relays with contacts rated for up to 30Amp, 250Vac load max. each. Optionally an internal alarm buzzer or up to two additional relays can be ordered for special applications to control loads of up to 10Amp, 250Vac max. each.
The high power and the optional relays' contacts can be wired up to control Heaters, HVAC and other loads like a Fan, Motor, Pump, etc...
All relays' contacts can be wired up as completely isolated from the controller's supply, so the supply voltage can be different than the voltages on the loads.
In order to switch very high loads, the relays' contacts can be wired up to control the coils of external contactors.
An additional, dry contact input can be ordered for external Start/Stop switch or other applications, like for instance a water level sensor switch.
Also, an additional, low voltage output can be ordered for max. load of up to 30mA, 5Vdc, for instance to connect to an external LED indicator lamp.
The controller is operated and the temperature and timer are preset by pressing the corresponding keys on the control panel face. The preset values are stored in internal memory.
A variety of the controller's operating configurations, temperature and timer ranges and limits are also programmable via the face plate keys.
In customized face plates the controller can have up to 9 push-buttons.
The 6-digit LED display shows the temperature and timer preset values, the current temperature, the timer count, and other indications of operation. The LED display can be ordered in RED, GREEN or BLUE color.
Another option is an external Remote Control and Display Panel ( SDR-4PB ) that can be connected to the main panel via a 4- or 2-conductor cable up to 500 ft ( 150M ) away.
Note, that the SD-4PB sauna controllers are designed to eliminate almost completely the EMF ( Electro Magnetic Field ) radiation.
