Speed Selection and Controls
These recirculation models are equipped with a 3 speed control, low medium and high, (Note - 1000RHC/RHCAC must be set to high speed when air conditioning is required), as well as a lighted on/off switch and a low voltage terminal strip. The low voltage terminal strip is used to connect the supplied dehumidistat.
Air Conditioning (DX) Coil
Model 1000RHCAC Only
The Direct Expansion (DX) Coil located inside the cabi- net is designed to dehumidify the incoming fresh air from the outside and is not intended as an air condition- ing unit for the space. The coil must be connected to an outdoor condensing unit, (this unit or it’s controls are not provided by NUTECH). Special care and atten- tion should be given to ensure the Model 1000RHCAC is set to high speed during air condi- tioning mode, to avoid the coil from freezing up.

Hydronic Reheat Coil
Model 1000RHC and 1000RHCAC | DISCLAIMER |
The coil is designed to temper the air delivered through the HRV, to room temperature and is not a heating appliance for the space.
Special care and attention should be given to selecting a thermostat which will be connected to the pump feeding the coil. The thermostats function will be to signal the pump to send water through the system if temperatures drop below 40˚F (5˚C) to prevent the coil from freezing and also to shut the pump off if the air temperature leaving the coil exceeds 77˚F (25˚C) to prevent over heating motors.
Thermostats and pumps not available from NUTECH.
The Model 1000RHC and RHCAC is intended to be installed by certified HVAC trades people. Damage resulting in partial or complete failure of the Reheat/Air Conditioning portion is the respon- sibility of the installing contractor. Precautions should be put into place to avoid these coils from freezing or causing the motors to overheat or any other unforeseen problem not mentioned here.
The DX Coil is supplied with an orificing device suitable for 1.5 tons of air conditioning @ 95˚F 80% RH inlet air.
