EvoControl Ventilation – MPO1 Display

205 Neutralzone Kyla

Setting the neutral zone before controlling the cooling signal.

210 - 214 Setpoint temperature

Setting of temperature setpoints in different operating modes.

240 Type of post-heating (post-processing)

By:

• Reheat not active.

Ext el:

• External electric battery is controlled by the thermostat output, 0-10 volts.

Int. El:

• Pulse control of internal electric battery via relay output.
• The rotor must have been constantly switched on for 3 minutes before the electric battery is switched on for the first time.

Water battery:

• In case of water coil, terminals 16 and 17 are used for circulation pump heating.
• Circulation pump heating is stopped if the heating control signal is below 0 % for more than 5 minutes and the outdoor temperature is above +5°C.
• The circulation pump is exercised for 5 minutes every 48 hours, the first exercise is done after 48 hours.

245 Return water temperature maintenance

When the unit is stopped, the return water temperature is maintained at the set value via the return water sensor.

246 Freeze monitor alarm limit

If the return water temperature falls below the set value, an alarm is triggered. At 5°K above the alarm limit, the shunt valve starts to force open.

The freeze guard is self-reversing.

250 Pre-heater

AV:

• At Off, terminals 17 and 18 are constantly off.

Pre-heating:

• In Preheat, terminals 17 and 18 are activated when the outdoor air temperature falls below the set value.
• Fixed hysteresis +/- 2°C.

251 Activation of preheater

Outdoor temperature for activation of preheater.

260 Supply air regulator P-Band

The P-Band of the controller applies from max cold to max heat. The P-Band is allocated on a percentage basis as follows:

• Cooling 30 per cent.
• Neutral zone, adjustable in °K.
• VVX 20 per cent.
• Reheat 50 per cent.

261 Supply air controller I-Tid

The integration time of the controller.

262 Mines restriction

Minimum supply air temperature limitation (applicable in all control modes).

263 Maximum limitation

Maximum limitation of supply air temperature (applicable in all control modes).

264 Low temperature alarm supply air

If the supply air temperature is below the set value, the alarm is cancelled after the alarm delay time set in parameter 917.

266 High temperature alarm Post-heating

If the supply air temperature is above the set value, the alarm is cancelled after the alarm delay time set in parameter 937 and there is no need for reheating.
