When using the supply air heater, the supply air sensor (TJ) must be installed downstream the heater (or cooler) at the length
of sensor cable allows or up to the first branching or bend of air transportation system.
Only heaters with up to 0.6 kW power circuit can be connected directly to the control board. The heaters of higher power heaters must be con-
nected to separate electric power circuit.
8.1.3. VERSION S300
SMARTY air handling units are able to control one heater or preheater coil at a time. When the preheater is used, one more temperature sensor
has to be installed to the system. After connection, configuration has to be performed. For more information see section "ACCESSORIES SETUP
(VERSION S300)".

In order to use a heating coil, following signals are required to be connected to the control board:
1. Electric heating coil command;
2. Heating coil overtemperature detector;
3. Heating coil position signal.
Output digital relays 24-230 V AC, max 6.3A, normally open/closed
NOTE: Power supply for the heater is not shown.

Electric heater must be installed inside the air duct. The layout is based on airflow direction ELECTRIC HEATER > SUPPLY AIR SENSOR (TJ).
When using the supply air heater, the supply air sensor (TJ) must be installed downstream the heater (or cooler) at the length
of sensor cable allows or up to the first branching or bend of air transportation system.
8.1.3.2. PREHEATER
In order to use a preheating coil, following signals are required to be connected to the control board:
1. Electric preheating coil command;
2. Air temperature after preheating coil;
3. Preheating coil overtemperature detector;
4. Preheating coil position signal.
