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.
Hydronic Reheat Coil
Model 1000RHC and 1000RHCAC
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.
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.
DISCLAIMER
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.
