How to Set Up a Sauna with Pre-Heating Function

Inlet can automate sauna access by connecting the access control system with a booking software. Customers can choose and combine any lock system and software system from our list of integration partners. Be sure to think about different use cases when selecting both the locks and booking system.
 

First, the locksmith/installer must use our setup guides to install the access control system correctly. Here you will find documentation for every lock and access control system we support. Inlet Premium is also required for a sauna with heating control.

 

When INLET has established a connection to the locks, API keys and Lock-IDs will be generated and sent to the software system to complete the installation.  After a period of testing, the complete solution is ready for use.

 

Inlet can also automate the sauna oven to start in pre-defined times related to the bookings. This can significantly reduce energy usage.

 

For onboarding of customers using the pre-heating solution, we need to know how long in advance of the booking start the oven should be turned on (how long the oven remains on after it is turned on is setup by either the locksmith, electrician, some other entity out of our control. This needs to be organized between the customer and that provider). 

To achieve this, please refer to the text below.

 

Proper use of sauna heater in conjunction with INLET and lock system

Inlet offers the possibility to control the sauna stove in the following way:


● Inlet can initiate heating by sending a pulse signal to the access control system,
which will typically send a pulse from the lock system for 2-10 seconds (check what
the relevant lock system supports, as this varies from system to system and is not
something Inlet can control). This pulse is sent e.g. 15, 30, or 45 minutes before a
reservation starts. This is the only control point available.


● If seat reservation is active, we will group all bookings so that only one signal is sent
to the oven. However, there might be cases where a booking is made just before the
hour starts, and it will then be sent as a separate signal to the oven. It is therefore
important that the system supports multiple pulses in succession.


● We cannot send signals to terminate the heating after a reservation. Therefore, the
sauna heater must be programmed to respond to the pulse signal by starting a
countdown timer. The heater will then be active for a predetermined period of time.


● Each time a new pulse signal is received (e.g.15, 30, or 45 minutes before a new
reservation), the heater's timer must be reset and started again to prevent the heater
from turning off before the next reservation.


● A countdown timer will ensure that if the internet or lock system experiences
downtime, the heater will turn off at the end of the timer regardless of external
signals. This is both more fire-safe and leads to a saving on electricity costs.


NOTE: The Inlet system only supports this specific mode of operation. We cannot customize
the length or type of signals sent. If the sauna heater is not compatible with this mode of
operation, Inlet cannot control the heater.

Safety and correct operation must be prioritized.
