Ventmatika EKA - Service; Troubleshoo Ng; Warranty

IMPORTANT: If failure appears, power supply must be switched off and only then performed fault
eliminaon works.
No special service is required for electrical heaters, only to check electrical connecon not less than 1 me per
year.

Troubleshoong
No heang from
heater
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
Heater gives full
output, not by set
point
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
Automac circuit
breaker switching off
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.
Protecon thermostat
cut off
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).
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.
