1. Application
The device is designed to keep the air temperature in ventilation and air conditioning systems depending on the needs of the
premises.
2. Operation
The controller can manage the following units of the system:
- Water heating and cooling section, with proportionate actuators of the three-way valves through two analog signal 0 - 10V
for heating and 10 - 0V for cooling.
- Electrical section, divided into up to six levels, each level is controlled by relay output.
- Air section by incoming and outgoing fan and signal 0 - 10V for management of frequency inverters for fans.
Water heating and cooling section:
The zone of regulation "Zone_reg" is immediately before setpoint temperature in air duct "T_set". When the measured
temperature is less than the temperature determined by the zone of regulation "Zone_reg", to the actuator for "heating" is fed
maximum control signal 10V, and to the actuator for "cooling" minimal signal 0V. When reaching the the zone of regulation
will begin change of both control signal for heating and cooling (0 - 10V and 10 - 0V). The change of the signal is present until
the temperature is in the zone of regulation. When measured temperature is higher than the set temperature to the actuator for
"heating" is fed minimal control signal 0V, and the actuator to a "cooling" maximum signal 10V.
When closing the contact at the input for frost protection, output for heating is fed maximum signal 10V, and output for
cooling minimum 0V and both the fan is switched off immediately
Electric heating section:
When the measured temperature is less than the temperature determined by the the zone of regulation "Zone_reg", is
switched on all the levels and fed all the installed power.
When reaching the zone of regulation will start exclude part of the levels as the forward power is proportionality of the
temperature difference between the set and measured temperature in air duct (T_set - T). When the measured temperature is
higher than setpoint, all levels are switched off and do not transmit power.
When opening the contact from the input for block thermostat or input for a lack of air flow is immediately disconnected all
heaters.
Air section:
The device can manage incoming and outgoing fan, as the suction starts with 10 seconds delay.
Instead, fans may be used and two-position air valves. The controller is able to monitor the operating hours of the fans in
order to replace the filters after extended operation.
Also, the device can control and frequency inverter or speed regulator via an analog signal (0 - 10V or 10 - 0V) and signal
"stop" ( "open collector" - logical level 0V). (See programming "Service Settings" and "Specifications")
Change the fan speed depends on the temperature in air duct. The zone of regulation "Zone_reg" ". When the measured
temperature is less than the temperature determined by the zone of regulation "Zone_reg", is fed a control signal for the
minimum speed.
When opening the contact from the entrance to minimum flow, regardless of temperature given a signal for minimum
speed.
When the system is in stop mode fans remain working. another 60 sec., in order to prevent
overheating in the heating section.

4. Programming
When the controller is turned off, you can not move to programming and the display shows one of the following messages.
or
Attention! The controller can be switched on and off from the front panel or remote control input. The controller turns off
regardless of where there are stop signals, but can be switched only when both places have command START.
Depending on the message, the controller can be switched on:
- On message "System is off from external sw" - open socket connected to the inputs for remote control. (See programming
"Wiring and technical characteristics")
- On message "System is off from internal sw" - press and hold for 5 seconds. button "".
After switching displays the current mode "Ventilation" or "Heating" and can move on.
4.1 Manually setting the supply air temperature
With buttons "" or "" scroll until the display shows the set and the measured value:
Press "" to enter the programming mode, then the value of the assignment flashes. With buttons "" or "" may make
changes from "T_set_min" to "T_set_max". (See programming "Service Settings")
To confirm the changes again press "" or wait about 10 seconds for automatic recording.
4.2Formation of the seting by the room thermostat or room temperature.
4.2.1 Formation of the seting by the room thermostat
The room thermostats must be of analog type output 0 (4) - 20 mA.
The setting is automatically replaced by the "T_set_min" to "T_set_max" as a function of current of the room thermostat.
Display shows the following information:

4.2.2 Formation of the seting by the room temperature.
In this case, the converter is required (Pt1000 to 0 (4) - 20mA), which connects the terminals of the room thermostat.
The setting is automatically replaced by the "T_set_min" to "T_set_max" as a function of the room temperature. Maximum
setting is reached at measured room temperature less than 3 ° from the set and the minimum at equal or greater than the set.
Display shows the following information:
4.3Mode selection at work. With buttons "" or "" scroll until the display shows:

С With buttons "" or "" scroll until the display shows:
Where no fault signal is displayed above message:
Upon receipt of a a signal for failure showing the following messages:
- Activated blocking thermostat or appliance for lack of air flow
- Activated frost thermostat on the water section
- Reached hours of work to change air filters
After replacing the filters is necessary to reset the time for the next shift. Pressing "", appears "Reset time Fan" "No /
Yes" to choose "Yes".
