Product Usage Instructions

Radiator Control Mode

If the wireless thermostat is set to ‘radiator control mode’, it
functions as a programmable room thermostat and controls the output
to a separate heating zone valve via the channel terminals. Note
that in this mode, the heat source will be activated, but the
manifold pump will only be activated upon demand from an underfloor
heating circuit.

Pump Exercise Function

To prevent issues with pump seizing during periods of
inactivity, you can enable the ‘pump exercise’ function by setting
the dip switch SW3 to ON. This will operate the pump for 5 minutes
once every month.

Pump Delay Function

The pump delay function helps in ensuring that the electrical
thermal actuators have fully opened before activating the manifold
circulating pump. It introduces a 3-minute delay from activation to
allow the valves to fully open.

Commissioning Switches

These switches are intended for engineer use during
commissioning. They allow the activation of loops and testing of
electrical outputs for proper functioning.

Engineers Test Switches

The block of 12 dip switches is used to test each zone, boiler,
pump, and H/W outputs. Ensure all switches are in the OFF position
once installation is complete.

DIP Switches

There is a 3-way DIP switch with various functions like Pump
Exercise, Pump Delay, and RF Test Enable. In normal use, these
switches can be ignored and should be kept in the OFF position.

DIP Switch 1 – Pump Delay

To activate the pump delay function, switch DIP switch 1 to the
ON position.

DIP Switch 2 – Pump Exercise

To enable the pump exercise function, set SW2 to the ON
position.

DIP Switch 3 – RF Test

The boiler RF test switch is used for testing communications
with the RF-Switch receiver.

Frequently Asked Questions (FAQ)

Q: How often should I operate the pump exercise function?

A: It is recommended to operate the pump exercise function for 5
minutes once every month to prevent pump seizing issues.

Q: What is the purpose of the pump delay function?

A: The pump delay function ensures that the manifold circulating
pump is activated after a 3-minute delay from activation to allow
the valves to fully open.

TIOEVO0003

The TEVO wireless wiring centre from Tio Climate Solutions is an 8 zone wiring centre for use with TEVO wireless thermostats. Most commonly used for underfloor heating applications, the wiring centre can also be used for central control of multi-use systems by using the independent control outputs for hot water zone control and a dedicated channel for a radiator zone valve. The wiring centre can control the heat source activation through volt free output as well as offering a 230V output to the manifold circulating pump.
Other features within the wiring centre include: · LED indicators for quick system status checks. · Optional pump delay function to delay the pump activation during loop opening. · Pump exercise function to prevent pump blocking issues. · Commissioning switches for engineer testing.
The TEVO wireless system can be used as standalone UFH or combined with hot water and radiators. By selecting the thermostat system application during set up and pairing with the wiring centre, the system use case can be determined easily. With the TEVO wireless thermostat set to UFH control it will communicate with the selected zone/channel in the wiring centre and activate the UFH loop, manifold circulating pump end heat source. If the TEVO wireless thermostat has hot water mode’ selected the thermostat channel will act as a time switch and control the hot water output terminals. If the TEVO wireless thermostat hasradiator control mode’ selected it wi II act as a convention a I programmable room thermostat and control the output to a separate heating zone valve via the channel terminals.
Note: In radiator mode, the heat source will be activated but the manifold pump will remain inactive until a demand is given from an underfloor heating circuit.

Pump Exercise Function
During periods of inactivity (summer months or between installation and general use) a manifold circulating pump can seize and cause problems when the system is reactivated. To help prevent this issue, the TEVO wireless wiring centre has an optional `pump exercise’ dip switch (SW3) which, when selected to ON, will operate the pump for 5 minutes once every month.
Pump Delay Function
Commonly, the electrical thermal actuators which open the individual loops will take up to 5 minutes to fully open. The pump delay function will then delay activation of the manifold circulating pump by 3 minutes, from activation, in order to allow the vales to fully open.
Commissioning Switches
For engineer use only during commissioning. These offer the ability to activate loops and test the electrical outputs.
Engineers Test Switches
These are a block of 12 dip switches used to test each zone, boiler, pump and H/W outputs. To enable any output, put the switch in the ON position. When installation is complete, all switches MUST be in OFF position.
DIP Switches
There is a 3 way dip switch responsible for 3 functions: 1: Pump Exercise Function 2: Pump Delay Function 3: RF Test Enable In normal use, these DIP switches can be ignored and should be down in the OFF position.
DIP Switch 1
To enable the pump delay, put switch 1 to the ON position.
DIP Switch 2
To enable pump exercise function, put SW2 to the ON position.
DIP Switch 3
The boiler RF test switch is used to test communications with the RF-Switch receiver.
