Greenheck RV Quick Start Manual

Quick Start Guide
MODELS RV, RVE & RVC
This quick start document is intended to help complete the initial unit startup, but does not replace the IOM. Please read
the IOM for all safety information and precautions before performing any work on the equipment. See Model RV/RVE/RVC
Installation, Operation and Maintenance Manual. Complete pre-start checks prior to this procedure.
Damper & Fans
See Model RV/RVE/RVC Installation, Operation and
Maintenance Manual.
1. Verify discharge air sensor field installation at least three
to five duct widths downstream of unit discharge.
2. Verify proper phasing and voltage of incoming power.
See Figure 1 and LED status.
3. Jumper or install fire alarm contacts and remote start:
a. Install S6 fire alarm contacts or jumper terminal
[R] to [70] or [70P] to [701] Heat Cool Only (HCO)
Controls.
b. Verify S1 jumper [R] to [G] or if applicable, [R] to [Y1]
and [Y2]. For model RV-10 [C] to [G].
4. Enable Manual Override - Test Damper and Fans:
a. Press the program key on the unit controller.
b. Scroll to Ctrl Variables, press the
c. Scroll to Advanced, press the enter key.
d. Scroll to Login, press the enter key then down
arrow then enter to input password 9998. (After
login user is back in Advanced Menu).
e. Scroll to Manual Overrides, press enter.
f. Scroll to Manual Override Mode Enable [ ] press
enter then scroll to check Enable [x], press enter
again to confirm duration time.
g. When testing is complete, deselect Enable [ ] to
release all overrides and return to Auto.
5. Prevent components from starting in auto when system
is enabled by disabling fans, cool and heat devices using
Override: Auto to Manual, Command: Off, Value: 0%.
RV/RVE/RVC IOM DOAS START-UP REPORT
6. Press the program key, scroll to Unit Enable:
Enabled return to Manual Overrides Menu.
7. Override Damper signal to 35% and 100% to verify
that modulating OA damper matches signal and
re-circulation damper operates inverse of OA damper
direction.
8. Override Fan(s) On at 100%. Check rotation,
compare motor FLA to nameplate and record in
Start-up Report.
Air Tunnel Leak Detection & Fire Alarm System Verification
1. Overrides Off & Disable unit through main menu.
2. Remove A2L Mitigation Jumper between terminals [78]
and [79]. See Figure 2.
3. Supply fan forced to start and ramp to minimum required
airflow parameter via digital input on VFD.
enter key.
4. Alarm on controller indicates Airstream Sensor Trip.
5. Recirculation damper will remain open – If no
recirculation damper, the OA damper will open.
6. Compressor operation prevented via HPS circuit relay.
7. Bipolar ionization module will power off.
8. Remove fire alarm system contact or jumper at
terminals [R] to [70].
9. Fire alarm overrides A2L air tunnel mitigation response.
10. Verify supply fan(s) stop operation.
11. Reinstall A2L Mitigation Jumper and fire alarm contact
once all is proven.
