Warranty

1. Manufacturer declares 2 years warranty term from the date of manufacturer's invoice. Warranty is applied
in case if all requirements of transpor ng, storing, installa on and electrical connec on are fulfilled.
2. In case of damaged or faulty product during warranty term customer must inform producer in 5 days and
deliver product to manufacture as soon as possible at customer's costs. In other case warranty is not valid.
3. Manufacturer is not responsible for damages which occur during transporta on or installa on.
1. If the manual protec on is ac vated, check for a fault before pressing the RESET
bu on. If the fault is iden fied a er it has been rec fied, press the RESET bu on
using a screwdriver or similar object.
2. No power supply to heater – check all external electrical connec on components
(relays, switches).
3. Temperature sensor fault. Check sensor resistance, it must be 10kΩ at 25°C.
4. Pressure switch fault. Check if pressure in system is set correctly (check the
pressure when air flow is not less than 1,5m/s).
5. If LED 1 lights con nuously it means that there is a failure of: PTC (air velocity)
sensor, supply (TJ-K10K) or room (NTC10) air temperature sensor, poten ometer on
the top of the heater casing, wired remote control panel TR5K.
6. When the heater power supply is switched on, a er power supply interrup on or
a er any failure, controller is in preparing mode for 30 seconds.
7. PCB fault. Contact: quality@ventma ka.lt
1. Temperature sensor fault. Check sensor resistance, it must be 10kΩ at 25°C.
2. Air flow sensor fault. Check sensor resistance. It must be 22Ω between X15...X16
and 10Ω between X15...X18. Sensor must be clear.
3. When the heater power supply is switched on, a er power supply interrup on or
a er any failure, controller is in preparing mode for 30 seconds.
4. Triacs fault. Contact: quality@ventma ka.lt
5. PCB fault. Contact: quality@ventma ka.lt
1. Check circuit breakers data, it must correspond to heaters electrical data.
2. Check isola on of connec on cables, wires, check is heater grounded.
3. Check power supply source data, it must correspond to heaters electrical data.
1. Low air flow speed through heater. Check filters, fans, ducts of system.
2. Pressure switch fault. Check if pressure in system is set correctly (check the
pressure when air flow is not less than 1,5m/s).
