ROOFTOP  R407C

PACKAGED WATER TO AIR ROOFTOP UNITS

WITH SCROLL COMPRESSORS

rtr.w-rtp.w-GB•rel.1.3

MP Oversized microprocessor: compared to the standard micro-

processor, it allows a multi-language display reading, a more de-

tailed description of parameters, the possibility to manage up to 8

units, to manage non standard communication protocols, a better

access to the program, to manage free-cooling units (already in-

cluded in the units with option F).

MS Motorized dampers: motor controlled by an external 0-10V sig-

nal, if not dierently specied, when the standard version foresees

manual dampers (already included in the units with option F).

MTB Heating section with gas red burner: additional in-built sec-

tion, where one or more heating module of forced draft type are

installed, each made of a gas red burner and an air/smokes steel

exchanger. This module will heat the air to be introduced in the am-

bient, allowing the air to lick the external surface of the rebox and

the pipes of the exchanger. For the heat pump version this module

can be used as an additional heating section or, for an only cooling

unit, as an alternative to the heat pump itself. This section is realized

in conformity with the regulations in force.

MTC Heating section with boiler: additional in-built section, where

one or more boilers of watertight condensing type are installed,

producing hot water necessary to supply, through a close circuit,

a heating coil. The water circuit is complete with circulator, non re-

turn and check valves. This section is realized in conformity with the

regulations in force.

PA Rubber-type vibration dampers: bell-shaped vibration damp-

ers supports for insulating the unit (supplied in kit), made of base

and bell in galvanized steel and natural rubber mixture.

PF Water dierential switch: it stops the compressor in the case the

dierence between the inlet and outlet water pressure from the

plate exchanger is below a xed value, indicating that the water

ow is lower than the foreseen value

PM Spring-type vibration dampers: spring-type vibration dampers

support, for insulating the unit (supplied in kit), mainly indicated

for installation in dicult and aggressive environments. Made of

two steel plates containing a suitable quantity of harmonic steel

springs.

PQ Remote microprocessor: remote terminal, allowing to display the

temperature and humidity values detected by probes, the alarm

digital inputs, the outputs and the remote ON/OFF of the unit, to

change and program of the parameters, the sound signal and the

display of the present alarms.

RA Anti-freeze heating coil: electrical heating coil with thermostat

to protect the plate exchanger from freezing, in case of compres-

sors’ stop in the period of low ambient temperatures

RC Cross-ow heat recovery: cross-ow static heat exchanger with

aluminium plates, installed in a suitable section of the unit, so

to partially allow the transfer to the fresh air of the heating load

present in the exhaust air, increasing the energy eciency of the

unit. The exchanger has no moving components and therefore

there is no energy consumption: the two air ows involved are her-

metically divided and therefore there is no possibility of mixing. The

condensing water is collected in drain pans in stainless steel and

externally discharged. A by-pass damper is positioned side by side

to the heat recovery. On demand, the heat recovery section can

be realized in the 5 dampers version (please get in touch with our

Sales Dept.)

RE Electrical post-heating coil: electrical heaters of candle type with

carbon steel ns, placed after the evaporating coil; the electrical

heaters are used to re-adjust the air temperature to the requested

value, when the evaporator is used to lower the relative humidity in

the ambient. The coil is supplied by the electrical board of the units

and it is controlled by the microprocessor on a several step basis.

VP Pressostatic valve: device for the regulation of the condensing

pressure, through the control of the plate condenser water ow.

In case of cooling operation, the automatic valve reduces the wa-

ter ow when decreasing the condensing pressure, so to ensure

suitable working conditions also at a water temperature lower than

the nominal one. For the heat pump units, this option must be

installed with VSW in by-pass

VS Solenoid valve: electro-valve for the liquid refrigerant at the com-

pressor’s stop.

VSW Water solenoid valve: electro-valve stopping the water circula-

tion on the plate exchanger, when the compressor switches o. In

the case of heat pumps units provided with pressostatic valve (VP),

it is necessary to order this option (so to by-pass the pressostatic

valve in the winter operation).
