Heating modes for air heaters 
 
AUTOTERM Air Heater Work-modes
 
TEMPERATURE MODE:
 
Heater will maintain set temperature by reducing the heating power, without shutting off the combustion process.
 
POWER MODE:
 
Heater will operate constantly at set power level.
 
HEAT + VENTILATION:
 
Heater will operate till the temperature is reached 1°C above the set temperature, shut off the combustion process and start to ventilate till the temperature drops 5°C below the set temperature. When temperature drops, heating starts again.
 
THERMOSTAT MODE:
 
Heater will operate till the specified temperature is reached then shuts off the combustion process and ventilation. After the temperature drops by specified degrees heating will start again.
 
Heating modes for liquid heaters
 
PRE-HEATING MODE:
 
Heater will operate till the certain coolant temperature is reached then shuts off the combustion process. After the temperature of the coolant drops heating will start again.
 
ECO MODE:
 
(only for FLOW 14D)
Pre-heating mode with reduced power and fuel consumption. Temperature of the coolant is reached slower than in “Pre-heating mode.”
 
THERMOSTAT MODE:
 
(only for Flow 5)
 
Heater will operate till the specified interior temperature is reached then shuts off the combustion process. After the temperature drops by specified degrees heating will start again. Temperature is read by control panel.
 
*for setting up “Thermostat mode” see instructions for AIR heaters.
