The Hi-Velocity Systems Zoning Fan Coil 

features a superior design with simple setup options. 

Pre-wired multi-zone controls with adjustable power open and power closed actuators make it easy to 
understand and set up our zoning system. The fan coil can also be used with any off-the-shelf 24v 
thermostats. 

The 

HE-Z Zoning Package

 is designed for continuous air circulation when the thermostat is satisfied, 

allowing for increased filtration more even air temperatures and fresh-air make-up at all times. Hi-
Velocity Systems sets another high standard and energy efficiency in the residential & light 
commercial Forced Air Zoning Industry. 

Zoning Controls Features

Adjustable Zone Dampers - 

Power Open and Power 

Closed zone dampers are pre-wired and installed on 
the fan coil.

Zone Capacity - 

The main module controls three 

zones using motorized dampers and may be 
expanded  to 4 or 5 zones.

Compatible Controls - 

Controls single or two-stage 

hydronic heating systems, with single or two stage air 
conditioning.

Thermostats  - 

Compatible with off the shelf 24v 

Heat/Cool Thermostats.  Example (1heat/1cool) or 
(2heat/1cool).

Automatic Heat/Cool Changeover -  

Automatic 

changeover from any thermostat allowing for individual 
zone comfort.

Status LED - 

A green STATUS LED pulses as a 

steady heart beat to indicate Micro- processor activity 
and 24v power is present

System LEDs - 

Function specific colored LED’s 

illuminate to indicate the HVAC system mode of 
operation and active zone identification. 

Damper LEDs - 

Green LEDs labelled Zone 1 thru 

Zone 5 indicate which dampers are energized to the 
open position.

See Page 3 

for details.

Constant Fan Control -

 Any zone can activate the 

indoor fan and only the dampers in zones calling for 
continuous fan operation will open. Continuous fan 
operation will only occur when there are no active or 
pending, heat or cool demands.  

Internal Fuse

 (F1)- CAUTION:

 When the Internal 

Fuse is tripped it will get quite hot. To reset the Fuse: 

Shut off power to the fan coil and find and repair the 
short. Restore the 24VAC power.
