HRV200PLUS INSTALLATION INSTRUCTIONS

K. OPERATING MODES

The operating mode of the HRV200PLUS is determined by the status of the control inputs:

1. Fireplace Control Input Group

LO, HI, 12V, COM, C1, C2, R2, R1

2. Thermostat Control Inputs

TCOM, TSTAT

3. Ventilation Control Input Group

R, B, O, W, G

4. Furnace Interface Control Group

FNC, FCOM, FNO

The Fireplace Control Input Group represents the home owner’s desire for fireplace operation and are considered first priority by the HRV200PLUS controller. These inputs include signals from the fireplace dashboard controls, fireplace remote controls and dedicated hearth room thermostats. Inputs to activate the fireplace from this control group are processed with no regard to the other two input groups.

The Thermostat Control Inputs are used to couple the HRV200PLUS to the primary heating system to provide comfort heating when the temperature at the main thermostat falls below the set point. The Thermostat Control will not shut off the Fresh Air Fireplace if there is an input from the Fireplace Control Input Group.

The Ventilation Control Input Group receives signals from the ventilation controls installed with the system to maintain desired fresh air ventilation rates in the building envelope. Since the Fresh Air Fireplace operation requires continuous high speed ventilation, the Ventilation Control Inputs are ignored unless the Fresh Air Fireplace in not in use.

The Furnace Interface Control Group consists of a single pole, double throw set of contacts to provide an interface with the furnace control board and the main thermostat to enable furnace blower operation to distribute fresh air through the existing duct work.

1.Fireplace Operating Modes – Connector “P9”

a.OFF Mode

The HRV is idle until an input is sensed. This is the normal standby state when the HRV Plus is powered but not receiving any command inputs.

b.Fireplace High Fire Mode

All fireplace demands for fireplace operation from the hearth room result in a 12VDC signal sent to the HRV controller “HI” input terminal on the P9 connector strip. This includes the ON/OFF switch on the fireplace, demands from the fireplace remote control and heating calls from a dedicated fireplace thermostat.

Fireplace High Fire Mode is activated when 12VDC is sensed at the “HI” input terminal. The HRV/Fresh Air Fireplace system executes pre-purge and ignition processes as follow:

c.Caliber NXT Plus/6100 PLUS

1)Initiation

a)Blower motor on HIGH for system pre-purge.

b)C2 terminal is energized 12VDC activating the electric ember lights on the Fresh Air Fireplace.

c)Fifteen-second pre-purge timer activates while the HRV closes the alternate exhaust damper.

d)C1 terminal is energized 12VDC to override the pressure switch in the Fresh Air Fireplace.

e)R1 is energized 12VDC activating the IPI ignition circuit to initiate the fireplace ignition process. In the HRV, the R2 terminal must be jumpered to 12V to supply power to R1 at the Fresh Air Fireplace.

f)The thirty-second draft-proving delay timer activates.

g)The Fresh Air Fireplace lights.

h)The thirty-second draft-proving delay timer expires, C1 terminal is de-energized and the Fresh Air Fireplace pressure switch is monitored for sufficient flow at the flue collar for proper operation. IF SUFFICIENT FLOW IS NOT SENSED

AT THE FLUE COLLAR OF THE FRESH AIR FIREPLACE AFTER THIRTY SECONDS OF OPERATION, THE FRESH AIR FIREPLACE FLAMES WILL EXTINGUISH LEAVING THE ELECTRIC EMBERS ILLUMINATED ONLY. THE FRESH AIR FIREPLACE WILL NOT SUSTAIN NORMAL OPERATION UNTIL THE LACK OF FLOW IS CORRECTED!

HRV200PLUS specifications

The Hearth and Home Technologies HRV200PLUS is an advanced heat recovery ventilator (HRV) designed to provide optimal indoor air quality while ensuring energy efficiency. As homes become increasingly airtight due to modern construction techniques, the importance of proper ventilation grows. The HRV200PLUS addresses this need by continuously exchanging stale indoor air with fresh outdoor air, effectively maintaining a healthy living environment.

One of the standout features of the HRV200PLUS is its innovative heat recovery technology. This system captures the heat from the outgoing air and transfers it to the incoming fresh air. As a result, the air being brought into the home is pre-warmed, reducing the demand on heating systems during the colder months. This energy-efficient method helps homeowners save on heating costs while maintaining comfort levels inside the home.

Another notable characteristic of the HRV200PLUS is its quiet operation. Equipped with high-performance, low-noise fans, this unit operates in silence, ensuring that occupants can enjoy a peaceful environment without the disruptive sounds often associated with ventilation systems. Additionally, the HRV200PLUS provides versatile installation options, allowing it to be easily integrated into both new and existing homes.

The unit features adjustable settings that allow users to customize airflow according to their specific needs. With multiple fan speeds, homeowners can choose the most suitable option for their daily activities, ensuring an ideal balance between indoor air quality and energy use. Furthermore, the HRV200PLUS includes a built-in filter system that captures dust, allergens, and other airborne particles, enhancing overall air quality.

Durability and ease of maintenance are also keys in the design of the HRV200PLUS. Constructed with high-quality materials, this unit is made to last, reducing the need for frequent replacements. The filters are easily accessible, making periodic maintenance straightforward, which further extends the product's lifespan.

In summary, the Hearth and Home Technologies HRV200PLUS stands out as a premium choice for homeowners seeking a reliable and efficient ventilation solution. Its combination of heat recovery technology, quiet operation, customizable settings, and easy maintenance make it an ideal option for improving indoor air quality while keeping energy costs in check. As the emphasis on healthy living spaces continues to grow, the HRV200PLUS remains a practical investment for modern homes.
