The new CB500CO control box is the main element of the underoor heating/cooling control system.
It has a built-in module that controls the heat and cool sources. The control box allows you to control
5 dierent zones. The number of controlled zones can be increased up to 20 zones by using additional
CB500X extension modules (CB500CO main control box + three CB500X extension modules). Each
individual zone can be operated by one thermostat. The thermostat which requires a 230V power
supply has to be powered directly from the control box. The CB500CO has volt-free contacts designed
to control a boiler. The CO-Contact from the heat pump allows you to switch from Heating to Cooling.
The CO Contact can be volt-free or 0 respective 230V. It is equipped with 230V voltage outputs for a
pump and actuators. The spring clamps provide quick and convenient wiring connections. The control
box is designed to work with NC (normally closed) type actuators. It is recommended to mount it on
a surface or on a DIN rail.
Main fuse is located under the housing cover next to power supply terminals and secures the control
box and the devices connected to it. Use ceramic tube slow blow 250 V ROHS fuses (5x20 mm) with
nominal max current 10A. To replace fuse remove the fuse holder with a at screwdriver and pull out
the fuse.
Power supply for control box is 230 V ~ 50Hz.
Three wire installation should be made in
accordance with the current applicable regulations.
PUMP/VALVE output - this is a 230 V AC output that controls the pump and
valve of the heating and cooling systems. If any of thermostats connected
to the CB500CO send heating / cooling signal - PUMP/VALVE output will
be activated after 3 minutes. If all of the thermostats connected to the
CB500CO stop sending heating / cooling signal - PUMP/VALVE output will
be deactivated after 3 minutes.
This jumper sets the turn o delay time of the BOILER control
outputs.
Boiler output - this is a volt-free output (COM / NO) which controls heating
system boiler. If any of thermostats connected to the control box sends
signal for heating, BOILER output is activated after 3 minutes delay, giving
permission for boiler to turn ON. If all thermostats connected to the control
box stop sending signal for heating, then BOILER output is deactivated -
this is the signal for boiler to turn OFF (BOILER output can work with 0min
or 15min delay - please refer to chapter 4).
Boiler ON/OFF contacts
(according to the
boiler’s manual)
When the Pump/Valve control output is activated, the
LED shows a constant green light
When the BOILER output is activated, the LED shows a
constant green light.
WARNING!
Before starting the installation, disconnect the 230V power supply!
The LED will illuminatered
inidicating that the control box is
connected to the power supply.
NOTE: Replacement of the fuse to be carried out only when the control box is disconnected
from power supply (230 V ~).
NOTE: When the jumper is set to 15 minutes delay time you must ensure hydraulic ow in the
system when all actuators are closed. Use a bypass or dierential pressure valve.
This product complies with the essential requirements and other relevant provisions of the following
EU Directives: EMC 2014/30/EU, Low Voltage Directive LVD 2014/35/EU, RoHS directive 2015/863/
EU. The full text of the EU Declaration of Conformity is available at the following internet address:
www.saluslegal.com.
Use in accordance with current national and EU regulations. The product is intended for indoor use
only in dry conditions. The CB500CO should not be installed in areas where it may be exposed to
water or damp conditions. Installation must be carried out by a qualied person in accordance to
current national and EU regulations. Before attempting to setup and install, make sure that CB500CO
is not connected to any power source. Incorrect installation may cause damage to the control box.

When the jumper is set to position (default setting) then the BOILER output (volt-free “0 MIN”
relays) are deactivated immediately when thermostats stop heating.
When the jumper is set to position then the BOILER outputs (volt-free relays) are“15 MIN”
deactivated 15 minutes after thermostats stop heating.

If there is a need to increase the number of zones of the CB500CO control box, it is possible to connect the CB500CO and CB500X units using the EXTENSION connector. A maximum of three CB500X extension
modules can be connected to the CB500CO control box to have 20 zones. The connection between CB500CO and CB500X can be made in one way, in series as explained in point 1 or in parallel as explained
in point 2.
230V AC power is supplied only to the main CB500CO control box. Please pay attention to the terminal markings. All thermostats connected to the CB500CO or CB500X have an impact on the system module
which controls the heat / cool sources in the main CB500CO control box.
WARNING! DO NOT connect power supply to the CB500X power supply input when it is connected together with CB500CO. CB500X power supply input have to be used only when control box
extension works as standalone device.
HP VF contact - volt-free relays for Heat/Cool Changeover
When the Heat Pump changes into cooling mode will close the contact
and switch the CB500CO into cooling mode enabling 230V on all CO
contacts.
If the installation is equipped with a dew point sensor, it should be con-
nected to the DEW POINT contacts. When condensation is detected (DEW
POINT contacts closed), PUMP and HP/CHILLER contacts are switched o
immediately to prevent oor damage. DEW POINT contact is only active
in cooling mode.
Actuators wires should be plugged into the spring clamps of the respective zones. The maximum
current load for each zone is designed to handle up to 6 actuators with a power of 2W each. With
more actuators in one zone, an additional relay should be used to make sure that actuators output
will be not overloaded.
CB500CO only supports switching the thermostats between heating and cooling modes if their ther-
mostats support that feature (like our HTRP230V, HTRS230V, HTR230V, BTRP230V, and BTR230V). If
there will be live 230V on the CO terminal, the thermostat knows it has to switch to the cooling mode.

shows a constant light.red
NOTE: Depends on the thermostat

NOTE: When contact senses humidity above 95% will stop cool
mode and change immediately to Heat mode (careful that ther-
mostats are not set higher than room temperature, will keep the
actuator open)
NOTE: Only thermostat which have a CO contact can be used for cooling which require 230V
Input signal to changeover
NOTE:
• Minimum 3 contacts, L, N and “switch live” to work;
• When used also for cooling, CO needs to be connected;
• 0V on CO = Heatmode | 230V on CO = Coolmode
