The HVC0001/HVC0002 controller has been designed to control a single-speed bath fan. To suit the
user’s preference and lifestyle, it can be programmed in any the following modes of operation:
ENGLISH
• Manual Mode (see page 10)
• Daily On/Off Program Mode (see page 11)
• Customized Cycle Program Mode (see page 12)
• ASHRAE 62.2 Program Mode (see page 13)
Unlike the four programmable modes mentioned above, the Countdown Mode can easily be
activated by simply pressing a button. In this mode, the fan is always On. At the end of the
countdown, set by the user, the controller returns to the programmed mode (see page 14).
This controller cannot be used with a load lower than 0.1 A or higher than 2.5 A.
The controller can be used to control a bath fan’s built-in light or a separate light fixture
connected to the bath fan control circuit . However, the light cannot be in dependently
controlled and will turn On or Off at the same time as the fan.

Set the ASHRAE parameters
NOTE: Set the ASHRAE parameters before using the controller in ASHRAE mode .
When you power the controller for the first time, you will be prompted to set the following ASHRAE
parameters:
ENGLISH
• Measurement units selection (US or metric)
• No. of bedrooms (1, 2, ..., 6)
• Floor space (1000, 1100, ..., 5000 sq. ft. or 100, 110, ..., 500 m
• Fan capacity (30, 40, ..., 200 CFM or 15, 20, ..., 100 LPS)
If you do not touch any button, the controller goes to normal display after 60 seconds and you will be
prompted to set the ASHRAE parameters again the next time the controller is powered down and back
up. The ASHRAE parameters can also be accessed at any time.
NOTE: Refer to the ASHRAE parameter flowchart sheet on how to set the parameters.
After you have set the ASHRAE parameters, the controller will indicate whether you pass or fail to meet
ASHRAE 62.2 standards and will also indicate the percentage of time the fan will run based on your
ASHRAE settings. If this value exceeds 100%, the controller will indicate Fail; this usually means the fan
capacity is insufficient for your house.

Period to 10 minutes and the Idle Period to 20 minutes, you have established a
cycle of 30 minutes. During every cycle, the fan will turn On for 10 minutes and Off
for 20 minutes.
NOTE: Refer to the
