ii. ECM Fan on at calculated speed equal to 375 CFM per calculated ton of V-star compressor.
ECM fan will run for one minute at this speed then slowly modulate to maintain 55 degree
discharge air temperature.
iii. Loop pump off until Priority DHW satisfied or med limit trip (Med limit is a safety to protect
from low flow on hot water loop).
iv. DHW pump on
v. V-star compressor will ramp up as needed to keep space temp within a half of degree of
cooling set point. No additional compressor speed is added due to the ground loop pump
being in the off position. All the heat extracted from the space is transferred into the hot
water loop.
13.0 Recommended Hydro-Temp™ Start-Up Procedure
13.1 Start-Up Check List.
Verify the following items are addressed before starting the unit:
• If closed loop system, loop is purged and auto purge is filled to 3” from top of tank and all valves are open.
Ensure a minimum of 20% methanol or 25% Propylene glycol is purged into the loop and properly mixed.
Ensure all piping is verified to provide designed flow rate and all valves are open.
• If open loop system, well has pressure (20PSI – 50 PSI) and all valves are open. Make sure water flow stops
when system is off.
• All air is purged from hot water loop lines and all valves are open. A dry pump will quickly burn up. If
Priority On Demand system insure DHW tank sensor is properly installed.
• Optional U.V. light installed. (UVC must be powered down if panel is removed to area where light is
installed. Severe eye burn could occur)
• All supply and return grills are installed and unrestricted.
• All supply air dampers are installed and powered correctly. All dampers should power open if no zone is
calling for heat or cool.
• Return duct and grills are installed and unrestricted with filter installed.
• All service panels to air chamber are secured to unit.
• Supply voltage is correct and matches nameplate.
• Fuses, breakers, and wire sizes are correct.
• Low voltage wiring complete including all thermostats and field safeties.
• Unit is level for proper condensate drainage and a condensate drain is open, correctly pitched, and p-trap is
installed.
• Service / Access panels are in a place with proper clearance to allow service to front and sides.
• All Protostar installer settings are correctly configured.
