VATIRO T2000 Installation & Operation Manual

01 Identification, safety and use

This manual accompanies model VATIRO T2000. Record SKU, serial number, voltage, fuel and revision before installation. Accessories, functions and protective devices depend on the supplied variant.

Cabin heating for vans, work trucks, recreational vehicles and mobile equipment. Select according to insulation, climate, volume and air exchange.

Carbon monoxide: combustion gases must remain outside occupied spaces. Do not operate in a garage or other enclosed location. Keep intakes and flue outlets clear, especially after snow, mud or travel.

Fuel smell, abnormal smoke, leakage or a CO alarm: stop use, move occupants away and have the installation inspected. Do not restart to conceal a fault. Contact emergency services if there is immediate danger.

Fire and burns: keep combustible materials away from the appliance, hot ducts and exhaust. Do not use the service compartment for storage. Allow cooling before inspection and keep children away from hot surfaces.

Power: use the nameplate voltage. Never increase a fuse rating or bypass protection. For a normal stop, allow the controlled cooling cycle to finish before disconnecting power.

Stop before refuelling. Fuel, combustion, gas and mains work require a qualified professional. Install and maintain a CO detector suitable for the application according to its own instructions.

Air heating: cabin air passes through the heat exchanger and returns warm; it must remain separate from exhaust. Confirm duct size, length and resistance, return air, grilles and outlet protection. Do not close all outlets. No domestic-water circuit is documented for this family.

02 Variant specifications

Differences between variants

For unpublished values, use the supplied variant's nameplate and data sheet: starting current, fastening torque, pressure, pump flow and protection devices cannot be inferred from power.

03 Recommended applications and output selection

Select according to insulation, outdoor temperature, heated volume and air exchange. For domestic water: water demand, pressure and frost protection. Engine displacement and engine coolant volume are not applicable to this unit.

04 T2000 exploded view

Drawing callouts: identify components before service. A sectional view shows operation; it does not define a disassembly sequence. Check the unit revision before ordering any part.

05 Step-by-step installation

STEP 1 - Prepare and secure

Select a rigid base. Check clearance for ducts and maintenance. Position the supplied gasket and template before drilling. Separate the occupied area from the combustion area.

STEP 2 - Distribute hot air

Provide a clear return-air route. Secure ducts without crushing them and protect outlets from luggage. Avoid direct recirculation from the hot outlet to the inlet.

Mounting and kit components Circulation: correct / incorrect arrangement

STEP 3 - Install the fuel supply

Secure the tank, pickup, filter and pump compatible with the variant. Cut the tube cleanly; insert both ends until they meet inside the connector to avoid bubbles. Keep lines away from hot parts.

ACTION DETAIL - schematic

Insert both tubes until they meet.

Detail: no air pocket between tubes.

STEP 4 - Install intake and exhaust

Use the supplied ducts. Secure ends and direct gases outside the vehicle, away from openings. Provide condensate drainage according to installation; no water pockets or contact with a fuel line.

Fuel connection without air pocket Outlet orientation: correct / incorrect

STEP 5 - Connect and test

Connect the protected harness and compatible AT1192 controller. Check polarity and voltage under load. Perform ignition, steady operation and complete shutdown; check odors, leaks and overheating.

06 T2000 dimensions and connections

Position the template and gasket before drilling. Separate combustion intake and exhaust.

07 Electrical connections

Compatible controller Signal harness

Schematic. Pins, rating and voltage: use the supplied harness.

Maintain power during cooling. Normal shutdown uses the controller; do not install a switch that interrupts the cycle. Protect cables and connections against water, abrasion and heat.

Circuit detail for the illustrated family. Drawing labels identify components; check connectors, voltage and options on the supplied harness. A mains connection cannot be inferred from nominal power alone.

08 Initial commissioning

09 Operation and controls

AT1192 - controls for the illustrated air configuration. The coolant configuration uses its own menus.

On the documented OLED revision, a long press on the confirmation knob from the working screen controls on/off. The reference defines long as more than 2 s and short as less than 2 s. Confirm this behaviour on AT1192 before issuing customer instructions.

For the documented air heater, short-press to open mode selection, rotate to choose, short-press to confirm and use Back to exit. Reference modes are power, thermostat and ventilation. Do not transfer these modes to coolant heating.

The coolant panel has specific coolant-temperature and duration settings. Check the applicable ranges, durations, menus and thresholds for the ATLOSON unit on the rating plate and supplied variant sheet. Do not use shortcuts from an older seven-day timer on the OLED panel.

Clock and timers: confirm firmware-specific labels and sequence, set the clock and supervise a test schedule. Disable unused events. Priming, resets, Bluetooth and updates require the exact revision manual.

GSM: confirm module reference, available network, SIM, wiring, commands and status feedback. No SMS command is assumed here. The panel alone does not establish that cellular connectivity is fitted.

The supplied T2000 manual describes holding the knob for 2 seconds to start or stop, a short press to select and rotation to adjust. On the corresponding revision, “Variable Heat” selects P1-P7; “Thermostat” sets cabin air at 5-35 °C; “Ventilation” runs the fan only. Select modes with the heater completely stopped. Flashing “OFF” means cooling; a dark screen does not prove shutdown. These air modes must not be applied to coolant heating. Confirm panel and ECU revision if screens differ.

For the revision in the T2000 PDF, set “Time” first. With the heater stopped, open “Timer”, select the arrow beside “Timer1”, “Timer2” or “Timer3”, then set “WEEK”, “START”, “Duration”, “MODE” and its value; save with “OK”. The stated minimum duration is 10 minutes. S M T W T F S runs Sunday to Saturday. Selecting the program name enables/disables it; the arrow edits it. Review all three programs and perform an attended test. Disable every timer before refuelling, entering an enclosed workshop or a hazardous area. Confirm labels and limits on other firmware.

The gear button opens settings. “Information” exposes “Heater”, “Panel”, “Air pressure” and “Run time” where available. The T2000 PDF states: steady blue initializing; flashing blue communication lost; steady green operating; steady red stopping; flashing green fault. Photograph the message before leaving the screen.

GSM-compatible marketing does not include a module, SIM, service plan or protocol automatically. A “Bluetooth” menu does not establish GSM connectivity. Confirm hardware, network and exact commands; test remote control with an operator present.

10 Maintenance and winterization

Run for 10 minutes every month outside the operating season. Have the burner inspected at 800 hours. Internal work must be performed by a workshop using parts and tools for the variant.

Before use and after travel, inspect ducts, supports, openings, fuel lines and accessible connections. Once cool, remove external debris without directing water into the intake or flue.

Before the season and after storage, have the installation, battery, protection, tightness and combustion checked. Hour-based intervals, exercise-run duration and component life remain to be confirmed for the exact model and revision.

The user may keep access clear and clean cold surfaces using material-appropriate methods. Burner, exchanger, pump, sensor and ECU removal is qualified service work. Do not adjust fuel delivery or thermal protection.

After repair, require leak checks and a full cycle. Record date, hours, symptom, code, part SKUs and technician. Confirm applicable warranty terms with ATLOSON; other warranty policies are not transferred.

11 Troubleshooting and fault codes

Record the exact code before clearing it. Stop and allow cooling, check the power supply under load, then ducts and the fluid circuit. Correct the cause before a supervised test. A repeated fault requires workshop service.

12 Fault-code table - AIR

Table for the controller/ECU of this family. The same number may have a different meaning on another revision.

13 Parts, kits and purchasing

Order by part number and variant. Drawing callouts are not SKUs. Check voltage, fuel and connector before replacement. A complete-system reference is not a maintenance kit.
