* If complete Verso Pro electrical heater section is used, additional zone control modules are not needed and PM boards inside of electrical heater section
will be used for the same purpose.
2. INSTALLATION
For additional zone temperature control it is needed:
a) Zone module*
b) Supply air temperature sensor (for independent temperature zones or pre-heater control)
c) Return water temperature sensor (for water heater, when frost protection of the coil is needed)
d) Duct mounted heating/cooling device with additional components needed for its operation.
e) Connection cables
Zone module box can be installed in any place near external duct mounted heater/cooler, which will be controlled. It should
be prevented from direct water drops and sun. All the cables going in/out of the zone module box must be sealed ensuring
protection from humidity and dust.
When temperature maintenance is needed in different (independent) temperature zones, supply temperature sensor must
be installed after the heating/cooling device. In cases if zone module is used to control a preheater, temperature sensor must
be installed between preheater and the AHU. Supply temperature sensor should be mounted in the straight air duct after
heating/cooling device (or pre-heater) at a distance of at least of two duct diameters (or two diagonals of the rectangular
duct). In cases if zone module is used to control a preheater, temperature sensor must be installed between preheater and
the AHU. For outdoor units, when choosing a place for temperature sensor placement, please avoid direct sunlight which
can affect temperature readings.

When water heater is used as a heater or pre-heater, return water temperature sensor must be installed on the return water
pipe as close to the coil as possible and must be properly insulated, thus the surrounding temperature will not affect its
measurement. This sensor is used for frost protection of the water coil. If there is no need for frost protection (for example
ethylene glycol is used as a medium instead of water), return water sensor will not be used.
