OVERVIEW
1.0 OVERVIEW
1.1 CONTROL SEQUENCE OVERVIEW
The Renewaire ERV with premium controls provides outdoor air while saving energy by passing
the Exhaust Air through the energy recovery core to exchange energy with the incoming air,
with energy being passed to the incoming air in the winter and energy being passed to the
outgoing air in the summer. Pairing this with the factory-programmed premium controller
provides an excellent turn-key solution with the following control options.
1. Turning the unit off and on based on
u
A digital input (smoke detector, occupancy sensor, etc)
u
The controller keypad
u
Schedule
u
A BMS system, if the feature is enabled
u
CO2 level, if the feature is enabled
2. Isolation damper control (if option is included)
3. Supply and exhaust fan control
u
On/Off fan control for constant speed fans
u
Variable speed fan control for variable speed and ECM fans (set as a percentage)
u
Variable speed fan control for variable speed fans as a CFM reading
u
Exhaust fan tracking
u
Fan control based on CO2 or VOC levels (with optional sensor added)
u
Fan control based on space or duct pressure levels (with optional sensor added)
u
Single fan operation with digital input or BMS command
4. Supply and Exhaust Fan status via current sensors
5. Monitoring of these values
u
Outdoor Air (OA) Temperature
u
Outdoor Air (OA) Relative Humidity
u
Return Air (RA) Temperature
u
Return Air (RA) Relative Humidity
u
Supply Temperature (SA) before tempering
u
Exhaust Temperature (EA)
u
Supply Air CFM
u
Exhaust Air CFM
u
User-supplied CO2 or VOC sensors
u
User-supplied Room or Duct Pressure sensors
6. Monitoring of pressure across filter for filter status
7. Bypass control (with external bypass option) for frost control/economizer control
8. Control for added heating (additional Conditioned Air Temperature sensor required)
u
0–10V Gas or Electric
u
One- or two-stage Heat Pump
u
10-0V Hot water valve control
u
Control based on Supply or Return Air
u
Setpoint can be reset off Outdoor Air temperature
9. Control for added cooling (additional Conditioned Air Temperature sensor required)
u
0–10V chiller water valve
u
One- or two-stage compressor/heat pump
u
Control based on Supply or Return Air
10. VRF Control Sequence
11. Dual Temp Coil (using BMS command for heat/cool signal)
12. Alarm alerts and logging
NOTE: This unit has
a microprocessor
controller. It is com-
monly referred to as
a “controller.”
NOTE: Many of
these control
features require
the use of optional
sensors. The unit
configuration will deter-
mine the availability of
some functions.
