WV Rev. J Installation Overview
What unit BTU capacities are available?
There is only 1 size available, and it covers 2–5 Tons with a minimum load flow rate of 4.1 gpm.
What are the modes of operation?
Hot Water (DHW), Heat (Outdoor Reset), High Heat (Fan Coil/ High Mass), and Cooling.
What are the demand inputs for DHW, COOL, HHEAT, and HEAT?
The field terminal connections are all “DRY” contacts. If 24vac input is applied, it will cause damage to the controller.
What hydronic load side delivery features are internal to the WV unit?
Variable speed load pump, flow sensors, motorized ball valves, and new internal pressure differential bypass valve.
Do DHW and zoning controls come with the heat pump?
A thermistor is provided in the Turbomax for DHW temperature control (No external aquastat required). Load side zoning controls will need to be purchased separately.
What is the backup heating consideration?
The WV can be optioned with an internal 9Kw immersion heater or with dual fuel capability.
Can you control a modulating boiler for dual fuel applications?
Yes, boiler modulation can be done with 3-boiler output options. 0-10vdc, 2-10vdc, or 32-212F output signals to the boiler.
When installing the dual fuel version, do we need a secondary primary loop piping
No, this system was designed to plug and play with the boiler’s primary piping piped directly to the back of the WV unit. A boiler circulation pump will be required.
What are the unit’s physical dimensions?
41.927”H X 25”W X 28”D
Where are the water piping connections?
The WV unit utilizes flo-link double O-ring fitting for the source and load piping and the boiler connections are 1” FPT. The connections are located on the back side of the unit at an angle for ease of connection.
Why is a buffer tank not recommended on the load side?
This is a variable speed system, and it is designed to be “direct to load”.
Are there options for adding an additional load pump if needed?
Yes, a secondary load pump kit is available for applications with high head loss.
What main accessory is needed for Hot Water (HW) functionality?
Turbomax indirect tank is needed for domestic hot water generation.
Can the WV with the Turbomax tank produce 100% of the domestic hot water for the home?
Yes, if sized correctly. But remember “The system can only function one mode at a time”.
Antifreeze protection on both load and source?
It is required for both load and source for any and all applications. Fernox Alphi 11 Glycol is Enertech’s recommended antifreeze.
Do I need to flush the unit before powering it up?
The source piping can be flushed before power is applied to the unit. It is recommended to power up the unit without a heat or cool call and use the start-up wizard to assist flushing and purging air out of the load piping. The start- up wizard helps with the flushing process by shifting the internal motorized ball valves between hot water and house piping.
Is mitigation or RDS (Refrigerant detection system) sensors needed for the A2L refrigerant in the WV Rev. J?
No, the R-454B refrigerant volume is under M1 mitigation charge level of 62.6oz. – No refrigerant detection system or mitigation is needed for this equipment.
Are the Epic connected controls with the MyUplink platform installed on the WV Rev. J models?
Yes, the Epic controls will be factory installed on all WV units. Wi-Fi and an ethernet port are built-in to every WV Rev. J. The USB Connectivity Dongle needed for Wi-Fi connectivity comes included with each unit.
Where is the electrical panel located internally?
The electrical panel is factory orientated as a top mount but can be moved to the front of unit to allow for stacking units in racks. Electrical knockout connections can be found on either side or the back of the unit.
What is the clearance recommended for this unit?
Recommended 24” of clearance around serviceable areas.
