HI-LINE Super RC

12.0  Troubleshooting 

(continued...)

Common Installation Faults

For optimum performance, this unit must be correctly sized to
match the heat loss requirements of the space it is required to

heat, and the heating system must be correctly designed to 
provide adequate flow of hot water to the unit (see Section 2).
If the recommendations in Section 2 are not followed, 
problems may arise as detailed below.

Heating Mode -

No Fan

Heating Mode

(Heater model only)

poor heating 

performance and/or 

unit cycles on 

water sensor

Possible Causes

Unit switched off

Temperature set point reached

Unit not switched on at fused spur

Fuse blown at fused spur

Unit isolating valves shut

Water temperature reaching fan

convector below 32°C

(Heater model only)

Problem

Remedy

Low water temperature to unit

Turn up boiler thermostat

Poor water flow

Vent air from heating system

Turn on

Increase temperature set point

Switch on at spur

Replace fuse

Open valves

Check boiler -

Programmer ON

Boiler ON and set to high with central

heating pump running

Note:

Operation of fan convector can be checked by 

switching to manual fan setting

Heating Mode

(Heater model only)

poor heating 

performance and/or 

unit cycles on 

water sensor

Possible Causes

Boiler thermostat set too low

Lack of flow to fan convector -

Pump set on low setting

Isolating valves not fully open

System incorrectly balanced with unit starved of hot water flow

Pipe sizing to unit too small

Problem

Poor heating performance

(Heater model only)

Unit incorrectly sized for heat loss of room

13.0  Maintenance

Before undertaking any maintenance activity isolate the 
electrical supply.

Maintenance should be restricted to occasional removal of dust
and lint around the unit. The outer surface may be wiped over

with warm water and mild detergent taking care to avoid water
entering the grille areas.

If the fan convector is still faulty after checking the above, call your installer or MYSON Service.
