DESCRIPTION
PAGE 4
In order to ensure optimal use of the STROCO Electric heater and ensure maximum safety, it is im-
portant that this manual is read and understood before using the heater.
Please remember to complete warranty card at www.stroco.dk.
The Stroco Electrical heater is used to heat the vehicle during parking and day to day travel on hy-
brid or all-electric vehicles. STROCO Electrical heater is mounted in the vehicle's existing heating
system and can heat the driver's area, passenger space and engine. STROCO Electrical heater has
built-in heating elements operating thermostat and safety thermostat. The type designation 15 kW
indicates the power size of the heating elements in kW. The electrical connection to the electrical ele-
ments is made via a HVDC contactor (not supplied by Stroco) to the heating elements. The HVDC
contactor is controlled via the electrical mechanical contactor inside the connection box which re-
ceives an active 24VDC signal from the vehicle's heat control system to pull the HVDC contactor.
When the temperature is reached, the mechanical contactor breaks the 24 voltage to the HVDC con-
tactor. For circulation of the water, the 24V DC water pump is located on the heater and needs a 10
Amp secured cable connected to the heating control system

roughly. A minimum Ø3.5 mm even cutting or threading screw fitted with a tooth disc may be used.
2 Thermostat
Operating thermostat can be set steplessly from 37°C to 85°C. The thermostat has a built-in hystere
sis of 12 K, i.e. there is 12°C between the connecting and dissconneting. The operating temperature is
set with a screwdriver at . The safety thermostat disconnects if the temperature exceeds 110°C. The
thermostat can be reconnected by pressing the red button.
Note ! The setting and reconnection of thermostats must only be carried out with disconnected
main Switch of the vehicle.
