1. PC BOARD ADAPTER FOR HEATER CONTROL KIT - BRP4A50
When the installation of an electric heater is required in a cold region, this adapter with an internal timer function
eliminates the complicated timer connecting work necessary with conventional heaters.
Notes when installing:
Examine fully installation location and specification for using the electric heater based on the standards and›
regulations of each country.
Supply the electric heater and safety production devices (such as a relay and a thermostat etc) which meet the›
on site standards and regulations of each country.
Use a non-flammable connecting duct to the electric heater. Be sure to allow 2m or more between the electric›
heater and HRV for safety.
For the HRV units, use a different power supply from that of the electric heater and install a circuit breaker›
for each of them.
